Factors affecting the need for ureteral catheterization in symptomatic pregnancy hydronephrosis. Int Urol Nephrol 2024:10.1007/s11255-024-04052-2. [PMID: 38619779 DOI: 10.1007/s11255-024-04052-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Accepted: 04/05/2024] [Indexed: 04/16/2024]
Abstract
PURPOSE In our study, considering the clinical parameters we aimed to determine the most appropriate treatment approach for symptomatic gestational hydronephrosis and conditions requiring DJS insertion. METHODS Our study was a retrospective cross-sectional study and 137 patients were included. The patients were divided into two groups: those with conservative follow-up and those with DJS. Demographic and clinical data, the degree of HUN detected in urinary ultrasonography and the anteroposterior diameter of the renal pelvis were evaluated. Factors affecting the need for DJS between groups were investigated. Also, it was aimed to determine the cut-off value for the HUN degree and renal pelvis AP diameter in patients with DJS. RESULTS The presence of urinary system stones was statistically significantly higher in the group with DJS than in the group without DJS (p = 0.014). HUN degrees and AP diameter were statistically significantly higher in the DJS group (p < 0.001, p < 0.001, respectively). HUN degree and renal pelvis AP diameter were the two most important predictors for DJS insertion (p = 0.005, p = 0.015, respectively). The AP diameter cut-off value for DJS installation was determined as 20.5 mm. CONCLUSION Although there are conservative and surgical treatment options for symptomatic hydronephrosis of pregnancy, the factors at the decision point between these options are still a matter of debate. In our study, we concluded that the most important determinants at this decision point are the HUN degree and renal pelvis AP diameter. We think that the cut-off values we have determined for these markers will guide clinicians in deciding on treatment.

Effect of obturator nerve block during transurethral resection of bladder tumors on the disease recurrence, progression and surgery outcomes. Int Urol Nephrol 2023; 55:2765-2772. [PMID: 37531039 DOI: 10.1007/s11255-023-03727-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Accepted: 07/25/2023] [Indexed: 08/03/2023]
Abstract
OBJECTIVE In our study, we aimed to evaluate the effect of the obturator nerve block (ONB) on the operation time, duration of hospital stay, complete resection, presence of muscle tissue in the pathology, second resection, recurrence, and progression, when applied in addition to spinal anesthesia in patients with primary bladder lateral wall tumor and Transurethral Resection of Bladder Tumor (TURBT) was planned. MATERIALS AND METHODS Seventy patients with bladder lateral wall tumors were included in the study. In addition, ONB was applied to 35 of the patients who underwent spinal anesthesia. The two groups were compared in terms of obturator reflex development, perforation, complete resection, presence of muscle tissue in pathology samples, need for second resection, need for second resection due to inadequate muscle tissue, and 1 year recurrence and progression rates. RESULTS When the two groups were compared for obturator reflex and bladder perforation, both were found to be lower in the ONB group (p = 0.002, p = 0.198, respectively). The rate of complete resection and the presence of muscle tissue in the pathology samples were higher in the ONB group (p = 0.045, p = 0.034, respectively). The rates of second resection and second resection due to inadequate muscle tissue were found to be higher in the group without ONB (p = 0.015, p = 0.106, respectively). In the 1-year follow-up, the recurrence rate was significantly lower in the ONB group (p < 0.001), while there was no significant difference between the progression rates (p = 0.106). CONCLUSION In our study, we found out that ONB applied in addition to spinal anesthesia increases the rate of complete and muscle tissue resection by decreasing the obturator reflex, and causes a significant reduction in the need for second resection and tumor recurrence.

Impact of Preoperative Video-Based Education on Anxiety Levels in Patients with Renal Stones Scheduled for Flexible Ureteroscopic Lithotripsy: A Comparative Study Using APAIS and STAI. Med Sci Monit 2023; 29:e941351. [PMID: 37599431 PMCID: PMC10452046 DOI: 10.12659/msm.941351] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2023] [Accepted: 07/08/2023] [Indexed: 08/22/2023] Open
Abstract
BACKGROUND Anxiety prior to surgery can impact patient outcomes and satisfaction. In light of this, our study aimed to examine the effects of preoperative video-based information versus verbal information on anxiety levels among 60 patients with renal stones slated for flexible ureteroscopic lithotripsy. Anxiety was measured using the Amsterdam Pre-Operative Anxiety and Information Scale (APAIS) and the State-Trait Anxiety Inventory (STAI). MATERIAL AND METHODS We enrolled 60 patients with renal stones who were scheduled for flexible ureteroscopic lithotripsy. These patients were divided randomly into two groups: Group 1 (30 patients) received preoperative video-based information and Group 2 (30 patients) received only verbal information. Anxiety levels were assessed preoperatively using both the APAIS and STAI. On the first postoperative day, each patient indicated their pain using a visual analogue scale and filled out a questionnaire about their willingness to undergo the procedure again. RESULTS Group 1 exhibited lower anxiety levels as reflected by the APAIS scores for anesthesia (P=0.02), surgery (P<0.001), overall (P<0.001), and information needs (P<0.001). While there was no significant difference in the STAI-trait anxiety scores between the groups (P=0.15), Group 2 demonstrated notably higher anxiety levels concerning the surgical procedure, as measured by the STAI-state scores (P<0.001). The average pain score was 4.23 ± 2.17 for Group 1 and 5.37 ± 2.83 for Group 2 (P=0.08). Patients in Group 1 showed a greater willingness to undergo the surgery again (P=0.02). CONCLUSIONS Delivering preoperative information through videos significantly diminishes anxiety levels in patients about to undergo retrograde intrarenal surgery compared to traditional verbal communication.

The effect of screen time on the presentation and treatment of primary monosymptomatic nocturnal enuresis. BMC Urol 2023; 23:22. [PMID: 36803390 PMCID: PMC9936657 DOI: 10.1186/s12894-023-01184-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Accepted: 02/06/2023] [Indexed: 02/19/2023] Open
Abstract
BACKGROUND We aimed to investigate if there was any relationship between screen time (ST) and the severity of primary monosymptomatic nocturnal enuresis (PMNE) and treatment success. METHODS This study was conducted in urology and child and adolescent phsychiatry clinic in Afyonkarahisar Health Sciences University Hospital. After diagnosis patients were seperated by the ST for exploring causation. Group 1 > 120, Group 2 < 120 (min/day). For the the treatment response, patients were grouped again. Group 3 patients were administered 120 mcg Desmopressin Melt (DeM) and were requested < 60 min ST. Patients in Group 4 were given 120 mcg DeM solely. RESULTS The first stage of the study included 71 patients. The ages of the patients ranged from 6 to 13. Group 1 comprised 47 patients, 26 males and 21 females. Group 2 comprised 24 patients,11 males and 13 famales. Median age was 7 years in both groups. The groups were similar in respect of age and gender (p = 0.670, p = 0.449, respectively). A significant relationship was determined between ST and PMNE severity. Severe symptoms were seen at the rate of 42.6% in the Group 1, and at 16.7% in the Group 2 (p = 0.033). 44 patients completed the second stage of the study. Group 3 comprised 21 patients, 11 males and 10 females. Group 4 comprised 23 patients,11 males and 12 famales. Median age was 7 years in both groups. The groups were similar in respect of age and gender (p = 0.708, p = 0.765, respectively). Response to treatment was determined as full response in 70% (14/20) in Group 3 and in 31% (5/16) in Group 4 (p = 0.021). Failure was determined in 5% (1/21) in Group 3 and in 30% (7/23) in Group 4 (p = 0.048). Recurrence was determined at a lower rate in Group 3 where ST was restricted (7% vs. 60%, p = 0.037). CONCLUSION High screen exposure may be a factor for PMNE aetiology. And also reducing ST to a normal range can be an easy and beneficial method for treatment of PMNE. Trial Registration ISRCTN15760867( www.isrctn.com ). Date of registration: 23/05/2022. This trial was registered retrospectively.

Abstract
Background In in vitro studies, it is desirable that the storage solutions in which dental samples kept between extraction and experiment should prevent dehydration and have antimicrobial properties. However, it should be taken into consideration that these solutions may have some effects that directly change test results on physical and mechanical properties of laboratory samples. Aims The aim of this in vitro study was to evaluate the effects of different storage media on dentin moisture, microhardness, and microshear bond strength of resin composite to dentin. Thirty non-carious human premolars were randomly divided into three groups: 1. 0.1% Thymol (T), 2. Distilled water (DW), 3. Dry storage (DS) (control) (n = 10). Dentin moisture was measured with a digital grain moisture meter. Dentin microhardness was measured with the Vickers test. The bond strength was measured with a microshear test. Materials and Methods Analysis of variance (ANOVA) followed by the Bonferroni test was used for statistical evaluation (p = 0.05). Results Dentin moisture of the experimental groups was statistically higher than that of the control group (p < 0.05). In addition, the dentin moisture of group DW was significantly higher than that of group T (p < 0.05). The mean microshear bond strength of resin composite to dentin was higher in group DW than in group T and group DS (p < 0.05), while there was no statistical difference between group T and group DS. The microhardness values of all groups were statistically similar. Conclusions Storage solutions used for disinfection and to prevent dehydration may have negative effects on dentin moisture and bond strength.

Abstract
OBJECTIVE We aimed to investigate the significance of time to re-staging transurethral resection (re-TUR) on recurrence and progression rates in patients with high-risk non-muscle-invasive bladder cancer as a prospective randomized study. METHODS The patients were randomly separated into three groups according to Re-TUR timing. In Groups 1, 2, and 3, the time interval between initial and re-TUR was 14-28 days, 29-42 days, and 43-56 days, respectively. Cox regression analysis was used to assess the effect of time from initial TUR to re-TUR on oncological outcomes. RESULTS Twenty patients in Group 1 (14-28 days), 22 patients in Group 2 (29-42 days), and 29 patients in Group 3 (43-56 days) completed the study. Kaplan-Meier plots showed no differences in recurrence-free survival (RFS) and progression-free survival (PFS) rates between the three groups. Cox regression analysis demonstrated that only tumor number was found to be a prognostic factor on RFS rates. CONCLUSION Our prospective study demonstrated that time laps from initial TUR to re-TUR did not significantly affect on RFS and PFS rates.

Abstract
Objective: The present study examines the effects of the coronavirus disease 2019 pandemic on radical prostatectomy performed as part of localized prostate cancer treatment in Turkey. Material and methods: A retrospective analysis was made of the data of 176 patients from 8 centers in Turkey who underwent radical prostatectomy due to localized prostate cancer over the 2 years spanning March 1, 2019, to February 28, 2021. Within this timeframe, March 1, 2019, to February 28, 2020, was denoted the 1-year pre-coronavirus disease 2019 period, while March 1, 2020, to February 28, 2021, was denoted the 1-year coronavirus disease 2019 period. An analysis was made of whether there was a difference in the number of radical prostatectomies performed for prostate cancer, the time from biopsy to operation, and the biopsy and radical prostatectomy pathology between the 2 periods. Results: It was found that the number of radical prostatectomies performed for localized prostate cancer during the coronavirus disease 2019 pandemic was statistically and highly significantly fewer than in the pre-coronavirus disease 2019 period (P < .001). The patients diagnosed with Gleason 3 + 3 (low risk) prostate cancer were statistically significantly fewer in number in the coronavirus disease 2019 period (P < .001). The pathological Gleason score was upgrading than the biopsy Gleason score in all patients who underwent in both periods (P < .001). When the periods were compared, the pathological involvement determined by lymph node dissection performed during radical prostatectomy was found to be decreased in the coronavirus disease 2019 period, although the difference was not statistically significant (P = .051). Conclusion: As with many diseases, the diagnosis and treatment of prostate cancer have been adversely affected by the coronavirus disease 2019 pandemic.

Abstract
Objective In this study, we aimed to determine if there was any relationship between patients with erectile dysfunction (ED) who do not seek medical help at the hospitals and their health literacy (HL) levels. Materials and methods The study included 68 patients. Patients with a main complaint of ED were included in Group 1, and those with benign prostatic hyperplasia (BPH) or who requested an age-related check-up were included in Group 2. Questions 1-5 and 15 of the International Index of Erectile Function (IIEF)-15 scale evaluating erectile functions were collected as IIEF-6 for the purpose of this study. Severe ED was defined as having a score of 0-10, while moderate ED was defined as a score of 11-16. Both patients with severe and moderate ED were considered and included in the study. The European Health Literacy Scale (HLS-EU) and the Turkey Health Literacy Scale-32 (THLS-32) were used for the evaluation of HL. Results The HLS-EU person-specific mean index was found to be 37.22 ±5.29 in Group 1 and 30.46 ±6.32 in Group 2. The THLS-32 person-specific mean index was determined to be 37.68 ±5.41 in Group 1 and 30.94 ±6.13 in Group 2. In Group 1, 58.3% of patients were classified as having sufficient HL and 22.2% were classified as having excellent HL. In Group 2, 21.9% of patients were classified as having sufficient HL and 3.1% were classified as having excellent HL. Conclusions As societal income, education levels, and HL levels increase, ED will become more important to individuals, motivating them to seek timely medical attention, and thereby leading to earlier diagnoses of potential primary pathologies.

Abstract
PURPOSE To create a prediction model that could preoperatively measure the success of the transurethral prostate resection (TURP) because of bladder outlet obstruction. METHODS Patients aged 50-80 years applied with TURP were examined prospectively and evaluated in respect of the preoperative and postoperative values of maximum flow rate (Qmax), international prostate symptom score (IPSS), quality of life (QoL) score and post-voiding residual (PVR) urine amount. On the preoperative transabdominal ultrasonography, total prostate volume (TPV), and protruding prostate lobe volume (PPLV) were measured and the protruding ratio (PR), as the ratio of PPLV to TPV, was calculated. Based on the mean of the preoperative and postoperative Qmax difference (Qmax-D) value, Group 1 (n = 33) was defined as "low efficacy" and Group 2 (n = 30) as "high efficacy". RESULTS A correlation was determined between the QMax-D, IPSS difference, PVR difference, and QoL difference measured for the efficacy of the operation, and TPV, PPLV and PR. The results of multivariate analysis showed the main effect to be created by PR (p = 0.000; OR 1.596). In the evaluation with receiver operating characteristic curve analysis of high efficacy obtained in the TURP, a significantly powerful effect of the measurements of PPLV area under curve (AUC 0.922 [0.855-0.989] p= 0.000) and PR (AUC 0.954 [0.982-1.000] p = 0.000) was determined. The cutoff value of 11.5 was detected for PR. Efficacy sensitivity and the positive predictive values were recorded as 93.3%, and specificity and negative predictive value as 93.9%. CONCLUSION When determining candidate patients for TURP surgery, measurements of the PPLV and especially the PR should be taken into consideration in the preoperative prediction of efficacy.

Abstract
PURPOSE Comparison of efficiency and reliability of percutaneous nephrolithotomy (PNL) and retrograde intrarenal surgery (RIRS) in treatment of multicalyceal and multiple renal stones in the same renal unit. MATERIALS AND METHODS Between 2011 and 2015, records of patients who underwent surgery for renal stone were retrospectively reviewed. Patients who had multiple stones located in different calices in the same renal unit were included. The patients that underwent PNL and RIRS were defined as Group I and Group II, respectively. Patient criteria (age,sex); the stone characteristics; time of procedure, fluoroscopy and hospitalization; stone-free and complication rates of groups were evaluated between the treatment groups. RESULT There were no significant differences in terms of age, gender, BMI, laterality, number of stones, number of stone localization, hounsfield units and surface area characteristics of the stone between the PNL (n = 47) and RIRS (n = 35) groups (P = .558, P = .278, P = .375, P = 0.051, P = .053, P = .064, P = .642, P = .080, respectively). Stone free rate was 59.6% (n=28) in PNL, and 88.6% (n=31) in RIRS (P=.004). 1st or 2nd degree complications according to Modified Clavien Classification developed in 10 patients (21.3%) in Group I and 1 patient (2.9%) in Group II (P = .015). The 3A or 3B complications were similar in groups (P = .077). Time of procedure, fluoroscopy and hospitalization were significantly lower in Group II (P < .001, P < .001 and P < .001, respectively). CONCLUSION RIRS is more effective and more reliable procedure than PNL with higher stone-free and lower complication rates in treatment of multicalyceal and multiple stone in the same renal unit.

Abstract
OBJECTIVE To investigate the effect of papaverine and alprostadil on testicular torsion-detorsion injury in rats. MATERIALS AND METHODS A total of 40 male Wistar-Albino rats were used in this study. Four hours of right testicular torsion was applied to each group, excluding sham operated group. The torsion-detorsion (T/D), T/D + papaverine and T/D + alprostadil groups received saline, papaverine and alprostadil at the same time as surgical detorsion, respectively. At 14 days after the surgical detorsion, ischaemic changes and the degree of damage were evaluated with Cosentino scoring and the Johnson tubular biopsy score (JTBS). RESULTS JTBS was determined as 8.8±2.7 in the Sham group, 5.08±1.9 in the T/ D+papaverine group, 5.29±2.3 in the T/D +alprostadil group and 2.86±1.9 in the TD group. The JTBS was determined to be statistically significantly high in both the T/D + papaverine group and the T/D + alprostadil group compared to the T/D group (p=0.01, p=0.009). In the T/D + papaverine group, 3 (43 %) testes were classified as Cosentino 2, 3 (43%) as Cosentino 3 and 1 (14 %) as Cosentino 4. In the T/D +alprostadil group, 5 (50 %) testes were classified as Cosentino 2, 3 (30 %) as Cosentino 3 and 2 (20%) as Cosentino 4. CONCLUSION The present study indicated that spermatic cord administration of alprostadil and papaverine showed a protective effect against ischemia/reperfusion injury after right-side testes torsion and histological changes were decreased after testicular ischemia reperfusion injury.

Abstract
This study presents a preliminary assessment of biodiesel production from waste sources available in the Kingdom of Saudi Arabia (KSA) for energy generation and solution for waste disposal issues. A case study was developed under three different scenarios: (S1) KSA population only in 2017, (S2) KSA population and pilgrims in 2017, and (S3) KSA population and pilgrims by 2030 using the fat fraction of the municipal solid waste. It was estimated that S1, S2, and S3 scenarios could produce around 1.08, 1.10 and 1.41 million tons of biodiesel with the energy potential of 43423, 43949 and 56493 TJ respectively. Furthermore, annual savings of US $55.89, 56.56 and 72.71 million can be generated from landfill diversion of food waste and added to the country's economy. However, there are challenges in commercialization of waste to biodiesel facilities in KSA, including waste collection and separation, impurities, reactor design and biodiesel quality.

Abstract
PURPOSE To investigate whether use of dutasteride, a 5-alpha reductase inhibitor, for at least four weeks preoperatively affected the blood loss during open prostatectomy (OP). MATERIALS AND METHODS Retrospective analysis was made of the data of 110 patients who had undergone OP. Group I comprised 50 patients that used dutasteride for 4 weeks preoperatively, and Group II comprised 60 patients that did not use the drug. The groups were compared in respect of age, total prostate specific antigen (TPSA) levels, prostate volumes, preoperative hemoglobin (Hgb) and hematocrit (Hct) levels, postoperative reduction of Hgb and Hct, percentage reduction in Hgb and Hct, and the administration of postoperative blood products. RESULTS No differences were determined between the two groups in respect of prostate volumes, TPSA, preoperative Hgb and Hct levels (P = .813, P = .978, P = .422, P =.183, respectively). Postoperative Hgb reduction was 2.19 ± 1.36 g/dL in Group I, and 2.5 ± 1.47 g/dL in Group II (P = .260). Hgb reduction was calculated as 16.4 ± 9.7% in Group I and 17.6 ± 9.7% in Group II (P = .505). Reductions in Hct were 5.8 ± 3.7% in Group I, and 7.3 ± 4.4% in Group II, and percent reductions were 14.8 ± 9.4% in Group I and 17.3 ± 10.2% in Group II (P = .068, P = .182, respectively). CONCLUSION The use of dutasteride before OP did not affect blood loss during surgery, therefore surgery should not be delayed for the administration of dutasteride to patients.

Abstract
OBJECTIVES To compare the success of the 'tubularized incised plate urethroplasty' (TIPU) and 'Onlay island flap urethroplasty' (OIFU) techniques for the repair of primary proximal hypospadias. MATERIAL AND METHODS A retrospective evaluation was made of the medical records of 68 patients with primary, non-complicated hypospadias, who were operated on in the Department of Urology, Ministry of Health Ankara Education and Research Hospital, between January 1997 and December 2012. Patients who underwent hypospadias surgery with TIPU were labelled as Group 1 and the OIFU technique as Group 2. Patient age, native meatus localization, operation time, diversion type, surgical success and complication rates were all assessed. Surgical success was evaluated with direct vision of voiding and uroflowmetry at the time of catheter removal, then at 2 weeks, 6 weeks, 6 months and 1 year. RESULTS Group 1 consisted of 43 patients and Group 2 of 25 patients. The mean age of patients was 6.4±3.1 years in Group 1 and 8.0±4.6 years in Group 2 (p=0.09). The mean operating time was significantly lower in Group 1. (Group 1- 104.8±16.8 min, Group 2-125.4±24.7min; p<0.001) The distribution of meatus localization was similar in both groups. At 1 year postoperatively, urethrocutaneous fistula was the only complication and the definitive success rates were 81.6% in Group 1 and 72% in Group 2. CONCLUSION Despite less frequent usage since the description and popularization of TIPU for proximal hypospadias repair, OIFU remains a valuable technique as a single-stage procedure in cases where the urethral plate is insufficient. Currently, both TIPU and OIFU are used successfully in the treatment of patients with proximal hypospadias.

Should manual detorsion be a routine part of treatment in testicular torsion? BMC Urol 2017; 17:84. [PMID: 28915866 PMCID: PMC5602835 DOI: 10.1186/s12894-017-0276-5] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2016] [Accepted: 09/05/2017] [Indexed: 11/17/2022] Open
Abstract
Background It was aimed to investigate the efficiency and reliability of the manual detorsion (MD) procedure in patients diagnosed with testicular torsion (TT). Methods A retrospective analysis was made of the data of 57 patients diagnosed with TT, comprising 20 patients with successful MD (Group I), 28 patients who underwent emergency orchiopexy (Group II), and 9 patients applied with orchiectomy (Group III). The groups were compared in respect of age, and duration of pain. The success rate of MD, the time of testicular fixation (TF), any problems encountered in follow-up, and follow-up times were analyzed in Group I. Data were analyzed with P-P pilot, Mann-Whitney U, Kruskal Wallis and Chi-square tests. A value of p < 0.05 was considered statistically significant. Results MD was successful and detorsion could be achieved in 20 of 26 patients. The groups were similar in respect of age (p = 0.217). The median duration of pain was 3 (1–8), 4 (1–72), and 48 (12–144) hours in Groups I, II, and III, respectively, and determined as similar in Groups I and II (p = 0.257), although a statistically significant difference was determined between the 3 groups (p < 0.001). TF was applied to Group I after median 10 (0–45) days, and no parenchymal disorder was determined in the median follow-up period of 21.5 (2–40) months. Conclusion MD that can be easily and immediately performed after the diagnosis of TT decreases ischemia time. This seems to be an efficient and reliable procedure when applied together with elective orchiopexy, as a part of the treatment.

Abstract
OBJECTIVE We aimed to compare the success and complications of ultra-mini percutaneous nephrolithotomy and micro-percutaneous nephrolithotomy techniques. METHODS We retrospectively analyzed data from 74 patients. Moderate-size stones were included in the study. RESULTS Forty-two patients were included in MPNL, and 32 patients were included in UPNL groups. Among our patient cohort, 42 (56.7%)were males, and 32 (43.3%) were females. The mean age of the patients was 40±13.2 years in the MPNL group, and the mean age of the patients was 42±14.1 years in the UPNL group. The mean stone size was 17±3.2 mm in the MPNL group and 16.4±3.7 mm in the UPNL group. The stonefree rates were 88.1% (37/42) and 90.6% (29/32)in the MPNL and UPNL groups, respectively; there was no statically significant difference between the groups. The mean hospital stay was 1.4±0.23 days in the MPNL group and 1.1±0.12 day in the UPNL group. CONCLUSIONS Two techniques have similar success and complication rates, and both may be preferred particularly in moderate-size stones. Our experience supports that our UPNL technique is safe and effective using with a standard ureteroscope.

Abstract
BACKGROUND Depending on hyphothalamic, hyphophyseal, and gonadal axis dysfunction, anovulatory irregular cycles occur and the probability of pregnancy decreases in the patients with chronic kidney disease (CKD). Maternal mortality and morbidity rates are increased in CKD patients; the risk of premature delivery is 70% and the risk of preeclampsia is 40% more than normal among those with a creatine level of >2.5 mg/dL. METHODS If a pregnancy is expected in the sequel of kidney transplantation (KT), a multidisciplinary team approach should be adopted and both the gynecologist and the nephrologist should follow the patient simultaneously. Among 3883 patients who underwent KT at Antalya Medical Park Hospital Transplantion Department between November 2009 and October 2016, the records of 550 female patients between the ages of 18 and 40 years were examined retrospectively; 31 patients who complied with these criteria were included in the study group. In 6 of these patients who had an unplanned pregnancy, medical abortion was performed after the families were informed about the possible fetal anomalies caused by the use of everolimus in the first trimester, and they were excluded from the study (pregnant group). The control group consisted of 43 patients who had a KT and became pregnant, and of those who had recently undergone KT and shared similarities regarding age, CKD etiology, duration of dialysis, and number of transplants. RESULTS In both groups, the ages of the patients, their follow-up span and dialysis duration, tissue compatibility, age of the donor, and time elapsed until the pregnancy was analyzed, whereas in the control group, creatinine levels in the first, second, third, and fourth years after the KT were reviewed. Additionally, in the pregnant group, creatinine levels of the first, second, and third trimesters; delivery week; birth weight of the baby; APGAR scores of the first minute; postnatal creatinine levels of first, second, and third years; and prenatal, maternal, and postnatal acute rejections were reviewed. We measured the creatine clearance by use of the Cockcroft-Gault formula in the pregnancy group before pregnancy and during delivery [Cockcroft-Gault formula: (140 - age) × body weight (kg)/72 × plasma creatine level (mg/dL) × 0.85]. CONCLUSIONS Pregnancy after KT is risky both for the mother and the baby; however, if planned and followed in coordination within an experienced center, both the pregnancy period and the birth process can occur without distress.

Abstract
BACKGROUND Urologic complications (UC) have gradually decreased in recent years after advanced surgical experience. The incidence of urologic complications varies between 0.22% and 30% in different medical studies. There is no routine usage of double-J stenting (DJS) during renal transplantation (RT) in the literature. It is a necessity, and optimal timing for stent removal is an important question for many transplantation centers. METHODS This study includes 818 renal transplant patients whose ureteroneocystostomy anastomoses were completed by use of the Lich-Gregorie procedure during a 2-year period at a transplantation center. We performed 926 renal transplantations at Antalya Medical Park Hospital Renal Transplantation Center between January 2014 and January 2016. The patients were divided into four groups according to the timing of DJS removal. RESULTS For group 1, removal time for DJS was between 5 and 7 days; group 2, Removal time for DJS was between 8 and 14 days; group 3, removal time for DJS was between 15 and 21 days; and group 4, removal time for DJS was later than 22 days. The patients were divided into two groups according to removal time of stent as 5 to 14 days and >15 days. DJS was performed again in the patients whose urine output was reduced during the first 5 days after removal of the DJS, whose creatine level increased, and whose graft ureter and collecting tubules were extended as an ultrasonographic finding. CONCLUSIONS There is no declared optimal time for the removal of DJS. The removal time was reported between postoperative first week and 3 months in some of the reports of RT centers, according to their protocols. We emphasize that the optimal time for the removal of DJS is 14 to 21 days after RT, based on the findings of our large case report study.

What happens to asymptomatic lower pole kidney stones smaller than 10 mm in children during watchful waiting? Pediatr Nephrol 2017; 32:853-857. [PMID: 28070668 DOI: 10.1007/s00467-016-3570-7] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2016] [Revised: 12/11/2016] [Accepted: 12/15/2016] [Indexed: 11/24/2022]
Abstract
BACKGROUND The optimal management of lower pole kidney (LPK) stones in children is controversial. The aim of this study was to determine the outcomes of children with asymptomatic isolated LPK stones smaller than 10 mm during follow-up. METHODS A total of 242 patients with 284 stones presenting at our institution between June 2004 and December 2014 with an asymptomatic, single LPK stone with a diameter of <10 mm were enrolled in the study. All children were assigned to receive first-line therapy and then categorized according to the need for medical intervention. Age, gender, stone laterality, stone size and type, associated urinary tract problems, and uncontrolled metabolic status were assessed as predictive factors of medical treatment for small (<10 mm) asymptomatic LPK stones. Stone-free rates were compared between interventions. RESULTS The mean age and mean stone size were 9.4 ± 1.9 years and 7.4 ± 0.6 mm at admission, respectively. Stone progression rate was 61.2%, and the mean time for intervention was 19.2 ± 4.6 months. Flexible ureterorenoscopy (n = 68) or micro-percutaneous nephrolithotomy (n = 4) were performed for 72 stones (25.4%; group 1), and extracorporeal shock wave lithotripsy was performed for 102 stones (35.9%; group 2). The stone-free rates were 81.8 and 79.3% in group 1 and 2, respectively (p > 0.05). The remaining asymptomatic stones (110, 38.8%; group 3) were managed by continued observation, and at the end of the observation time (mean 40.8 ± 20.8 months) the spontaneous passage rate was 9.1% in this group. In the multivariate analysis, stone size of >7 mm, concurrent renal anomalies, and stones composed of magnesium ammonium phosphate (struvite) and cystine were statistically significant predictors of the need for intervention. CONCLUSIONS Children with stones larger than 7 mm, renal anomalies, or stones composed of metabolically active cystine or struvite are more likely to require intervention, and those with asymptomatic LPK stones smaller than 10 mm can be managed by continued observation.

Abstract
PURPOSE To investigate the effect of respiratory induced kidney mobility on success of shock wave lithotripsy (SWL) with an electrohydraulic lithotripter. MATERIALS AND METHODS Between May 2013 and April 2015, 158 patients underwent SWL treatment for kidney stones with an electrohydraulic lithotripter. The exclusion criteria were presence of a known metabolic disease (such as cystinuria), non-opaque stones, need for focusing with ultrasonography, abnormal habitus, urinary tract abnormalities, and inability to tolerate SWL until the end of the procedure. Stones greater than 20 mm, and lower pole stones were also excluded. The movement of the kidneys were measured with fluoroscopy guidance. RESULTS The procedure was successful in 66.7% of the males, and 56.9% of the females. The mean stone size was 11 ± 3 mm in the successful group, and it was 14 ± 4 mm in the unsuccessful group. The mean stone mobility rate was 32 ± 10 in the successful group and 40 ± 11 in the unsuccessful group. Multivariate analysis showed that stone size and kidney mobility affected the success rate significantly, however Hounsfield Unit (HU) did not. CONCLUSION The current study shows the significant effect of kidney motion on the success of SWL. Further studies with different lithotripters are needed to determine the significance of kidney mobility.

Abstract
INTRODUCTION The developments in hypospadias surgical techniques and materials are intended to improve surgery outcomes and patient comfort. The aim of this study is to determine the effect of the Zaontz urethral stent (ZUS) (Cook Medical) on patient comfort and surgical success rates in children undergoing hypospadias surgery. METHODS A feeding tube was used to repair 46 cases of primary distal hypospadias, and ZUS (6F, 8F, and 10F in diameter) was used to repair to 31 cases of primary distal hypospadias between December 2009 and June 2011 in our clinic. ZUS was compared with the feeding tube in terms of surgical success rates and patient comfort in assessments made during postoperative periods. RESULTS The patients with ZUS were followed with a stent for seven days postoperatively, as were the patients with the feeding tube. There was no statistical difference between the two groups in terms of fistula formation (p>0.05). Patient comfort was evaluated by the Face, Legs, Activity, Cry, Consolability (FLACC) scale on the first and third postoperative days, and a statistically significant difference was observed in favour of ZUS on the third postoperative day (p<0.05). CONCLUSIONS Compared with a feeding tube in hypospadias repair, ZUS does not make any contribution to the urinary fistula rates. However, ZUS may have an advantage in terms of patient comfort in the postoperative followup. On the other hand, the small number of patients and the high price of the ZUS were the most important limitations. Prospective, randomized trials are needed to assess efficacy and cost.

Abstract
This study aimed to evaluate the effect of preoperative imaging techniques on the
success and complication rates of ureteroscopy. We performed a retrospective analysis
of 736 patients (455 males and 281 females), with a mean age of 45.5±15.2 years
(range, 1-88 years), who underwent rigid ureteroscopic procedures for removal of
ureteral stones. Patients were divided into 4 groups according to the type of imaging
modality used: group I, intravenous urography (n=116); group II, computed tomography
(n=381); group III, computed tomography and intravenous urography (n=91), and group
IV, ultrasonography and abdominal plain film (n=148). Patients’ demographics, stone
size and location, prior shock wave lithotripsy, lithotripsy technique, operation
time, success rate, and rate of intraoperative complications were compared among the
groups. There were no significant differences in success and complication rates among
the groups. The stone-free rate after primary ureteroscopy was 87.1% in group I,
88.2% in group II, 96.7% in group III, and 89.9% in group IV (P=0.093). The overall
incidence of intraoperative complications was 11.8%. According to the modified Satava
classification system, 6.1% of patients had grade 1, 5.1% had grade 2, and 0.54% had
grade 3 complications. Intraoperative complications developed in 12.1% of patients in
group I, 12.6% of patients in group II, 7.7% of patients in group III, and 12.2% of
patients in group IV (P=0.625). Our findings clearly demonstrate that ureteroscopic
treatment of ureteral stones can be safely and effectively performed with no use of
contrast study imaging, except in doubtful cases of anatomical abnormalities.

Abstract
OBJECTIVE According to the ICCS definitions, enuresis is defined by an intermittent, wetting during sleep after organic causes have been ruled out with a minimum wetting frequency of once per month. Previous studies reported a prevalence rate of 9-12%. Eighty to 90% of enuresis cases are identified as primary enuresis and are based on genetic predisposition, biological and developmental factors. On the other hand, secondary enuresis frequently arises from psychological factors. In this study we aimed to determine the prevalence and associated factors of nocturnal enuresis (NE) among primary school children. METHOD We initiated a prospective cross-sectional epidemiological study from January 2013 to May 2013 by sending a questionnaire to parents of 4250 school children, aged 6-13 years. The questionnaire consisted of three parts. The first part investigated the demographic characteristics of the child and family, such as age, gender, number of siblings, and enuresis history of the parents and siblings. The second part consisted of questions about the presence and frequency of bedwetting, presence of constipation/fecal incontinence, and presence of daytime incontinence (DI). The last part surveyed school performance and the effect of enuresis on quality of life of parents and children. Logistic regression analyses were conducted to determine the significant predictive factors for NE. RESULTS The overall prevalence of enuresis was 9.52%. The prevalence of NE among boys and girls was 12.4% and 6.5%, respectively. Daytime incontinence was present in 18% of children. Of enuretic children, 59.2% had a positive family history of enuresis. Constipation was found in 13.2% of children with enuresis and there was no significant association between NE and the presence of constipation. In addition, 48% of enuretic children had poor school performance. CONCLUSIONS The current study demonstrated that age, male gender, parents' history of enuresis, and siblings' history of enuresis were significant predictive factors for NE. The majority of the parents did not have adequate interest in enuretic children and most of the children were not treated. Physicians should inform parents of enuretic children with the aim of solving this problem to prevent future issues and development of adulthood lower urinary tract symptoms (LUTS).

Abstract
The aim of this study was to detect the presence of Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Mycoplasma hominis, Trichomonas vaginalis, and Ureaplasma urealyticum in genital specimens of symptomatic patients. This study also examined the role of U. urealyticum in infections of the lower genital tract. Cervical and urethral samples from 96 patients (46 males, 50 females) were tested using the Seeplex(®) STD6 ACE kit. Consent forms were received and a questionnaire was applied. All statistical analyses were performed using the SPSS statistical software program (version 17.0). Among the samples tested, at least 1 pathogen was detected in 49% of the samples; specifically, the rate of detection of U. urealyticum, M. hominis, C. trachomatis, N. gonorrhoeae, M. genitalium, and T. vaginalis was 29.1%, 10.4%, 8.3%, 7.3%, 6.3%, and 4.2%, respectively. U. urealyticum was detected as the sole pathogen in samples from 10% of female patients and 28.3% of male patients (p = 0.035). U. urealyticum was present in 54.5% (18/33) of samples in which a single pathogen was detected and 71.4% (10/14) of samples in which multiple pathogens were detected. Among men, significant differences in discharge, dysuria, and pruritus were not noted among those with negative results (84.6%, 69.2%, and 38.5%, respectively), among those positive for only U. urealyticum (100%, 66.7%, and 26.7%, respectively), and those positive for N. gonorrhoeae, C. trachomatis, M. genitalium, and T. vaginalis (100%, 93.3%, and 26.7%, respectively). Detection of U. urealyticum, either alone or together with other pathogens, in a symptomatic group of patients is an important finding, particularly in men.

Abstract
OBJECTIVE To analyze the predictive factors for intraoperative ureteral wall injury due to semirigid ureteroscopy (URS) used in the treatment of ureteral calculi. METHODS The data of 437 patients who had URS due to ureteral stones were prospectively analyzed. The ureteral wall injuries that occurred during URS were reviewed endoscopically at the end of surgery and divided into two groups as low grade (grades 0 and 1) and high grade (grades 2, 3, and 4) according to classification of ureteral wall injuries. Those two groups were compared for patient and stone characteristics and perioperative findings. RESULTS Ureteral wall injury was seen in 133 (30.4%) patients after surgery. According to the endoscopic classification of the lesions after URS, grades 0, 1, 2, and 3 injury were seen in 69.5%, 16.4%, 11.2%, and 2.7% of the patients, respectively. There were no grade 4 injuries in our series. Two groups showed statistically significant differences for the location (prox- vs distal and mid-ureter) and size of the stone (9.9 mm vs 14.03 mm), presence of preoperatively urinary tract infection (UTI) (12% vs 50.8%), needed balloon dilatation (9.8% vs 36.1%), duration of surgery (33.6 min vs 43.3 min), and surgical success rate (90% vs 76%) (p = 0.01, for all). Stone size, location, duration of surgery, and presence of preoperative infection were determined as independent prognostic factors for mucosal injury. CONCLUSION The ureteral wall injury grading system may be used for standardized reporting of ureteral lesions after ureteroscopy. Big, proximal ureteral stone, longer operation time, and presence of UTI are the risk factors for ureteral wall injury during URS.

Abstract
More than 1 million patients are estimated to have undergone transplantation in the past years. In recent years, living-donor kidney transplantation accounted for more than 50% of all transplantations. Kidney transplantation from living donors is regarded as a contradictory case to the "do no harm" principle as a major surgical intervention is performed on a normal and healthy person at the expense of recovery of the organ recipient. The purpose of this study was to investigate positive psychological experiences, specifically post-traumatic growth (PTG), among living kidney donors. The sample consisted of a total of 184 kidney donors. The age of donors ranged between 21-76 (mean, 50.76; SD, 10.93). In this study 67.9% of donors were female. The recipients on dialysis group had higher scores than the recipients who did not have dialysis; the mean difference was significant on the subscales of change in life philosophy, change in relationships, change in self-perception, and in the PTGI score. The donors with higher education levels received higher scores on the subscale of change in relationships in comparison with donors with low education. The donors who were married and older than 51 years had higher scores than donors who were not married or younger on the subscale of change in self-perception. This is a single-center study; this center performs more than 500 kidney transplantations per year. There is a good system and experience at each step before and after transplantation for donor and recipient and relatives. It is a really big potential trauma to donate a kidney to your relative; you can change this negative effect to a positive effect with a good system. The present study also showed that when compared with the scale's absolute midpoint, kidney donors in the study sample experienced moderate-to-high levels of PTG.

[PMID: 26571314] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Received: 03/02/2015] [Revised: 06/19/2015] [Accepted: 09/15/2015] [Indexed: 06/05/2023]
Abstract
PURPOSE We determine whether the lengths of benign and malignant cores affect cancer detection rates in patients with prostate cancer (PCa). MATERIALS AND METHODS We evaluated retrospectively 512 patients in our clinic who had undergone 12 core transrectal ultrasound (TRUS)-guided prostate biopsies. The cores were divided into two groups: one with cancer (group 1) and one without cancer (group 2). We also classified Gleason scores as poorly differentiated (scores of 7-10) and moderately differentiated (scores of 5-6); these scores were compared with each other in terms of the core length. The core lengths of the groups were compared using a Student's t-test. A P value of less than .05 was considered to be statistically significant. RESULTS Of the 512 patients, 76 (15%) had PCa. In total, we evaluated 912 cores of prostate biopsy samples from the 76 patients. Since 92 cores included insufficient tissue and rectal mucosa, we were not able to evaluate them. The remaining 820 cores were divided into two groups. Cancer was detected in 302 cores; 518 cores were benign in nature. The average core length in group 1 was 11.9 ± 4.4 mm, and the average core length in group 2 was 11.1 ± 5.1 mm (P = .015). The core lengths of poorly differentiated and moderately differentiated cancers were similar: 12.3 ± 4.2 mm and 11.7 ± 4.5 mm, respectively (P = .25). CONCLUSION Increasing cancer detection rates in cores may be related to core length in TRUS-guided prostate biopsies in PCa patients.

Abstract
OBJECTIVES To research the effect of listening to music during shock wave lithotripsy (SWL) on the patient's pain control, anxiety levels, and satisfaction. PATIENTS AND METHODS The study comprised 400 patients from three hospitals. Half of patients listened to music during their first SWL session but not during their second session. The other half had no music for the first session but the second session was accompanied by music. During all sessions, with and without music, pulse rates, blood pressure, State-Trait Anxiety Inventory-State Anxiety scores (STAI-SA), Visual Analog Scale (VAS scores for pain), willingness to repeat procedure (0 = never to 4 happily), and patient satisfaction rates (0 = poor to 4 = excellent) were assessed. RESULTS There was no statistical difference between the two groups in terms of blood pressure and pulse rates. In both groups, the STAI-SA and VAS pain scores were lower in the session when music was listened to (p < 0.001). The patients requested more SWL treatment be completed while listening to music and their satisfaction was greater. CONCLUSION Music lowered the anxiety and pain scores of patients during SWL and provided greater satisfaction with treatment. Completing this procedure while the patient listens to music increases patient compliance greatly and reduces analgesic requirements.

Abstract
BACKGROUND We analyze the results of renal transplantation among recipients older than 65 years old over a 4-year period (2008-2012) from a single renal transplantation unit and compare results with younger recipients. METHODS We retrospectively analyzed the outcomes of 2018 renal transplantations performed between November 2008 and December 2012. The χ(2) test was used for the comparison of categorical data, and the Student t test was used for the analysis of continuous variables. Patient and graft cumulative actuarial survivals were calculated using the Kaplan-Meier analysis and we tested for differences with the Mantel-Cox log-rank test. RESULTS Seventy-five (3.7%) recipients were aged ≥ 65 years with a median age of 68 (range, 65 to 82) years. Actuarial graft survivals at 1, 2, and 3 years were 93.8%, 92.5%, and 90.3%, respectively, for the <65 group and 89.7%, 88.1%, and 83.1%, respectively, for the ≥ 65 group (P < .03). Actuarial patient survivals at 1, 2, and 3 years were 96.3%, 95.5%, and 94.7%, respectively, for the younger and 91.8%, 90.2%, and 88%, respectively, for the older samples (P < .03). When graft survival was censored for patient death with a functioning kidney at 1, 2, and 3 years, the results were similar between groups with 95.5%, 94%, and 92.8%, respectively, for recipients aged <65 years and 94.7%, 89.2%, and 89.2%, respectively, for recipients aged ≥ 65 years (P = .213). CONCLUSIONS Our results showed that renal transplantation in selected patients older than 65 years was associated with good outcomes; this indicates that it seems safe and effective to treat end-stage renal disease in the elderly knowing there are acceptable rates of graft and patient survival.

Does Metabolic Syndrome or its Components Correlate With Lower Urinary Tract Symptoms in Benign Prostatic Hyperplasia Patients? Nephrourol Mon 2015; 7:e27253. [PMID: 26290850 PMCID: PMC4537616 DOI: 10.5812/numonthly.7(3)2015.27253] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2015] [Accepted: 03/12/2015] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Metabolic Syndrome (MS) has become a global public health and has been suggested to be a risk factor for Lower Urinary Tract Symptoms (LUTS). Studies evaluating the association between the rate of the MS and LUTS often showed controversial results. OBJECTIVES The purpose of this study was to reveal the relevance of MS and its components on the frequency and severity of the LUTS that were seen with Benign Prostate Hyperplasia (BPH) in Turkish men or not. PATIENTS AND METHODS In this study, 237 patients referred to urology policlinic with BPH were retrospectively scanned between April 2009 and April 2013. Patients with normal digital rectal examination and the Prostate Specific Antigen (PSA) level of ≤ 4 ng/mL were evaluated using the International Prostate Symptom Score (IPSS) and all the data of the patients' body, including Body Mass Index (BMI), lipid parameters, preprandial blood glucose, and waist circumference. Seventy-four patients (31.3%) with mild IPSS (0-7) was group 1; 97 patients (40.9%) with moderate IPSS (8 - 19) group 2 and 66 patients (27.8%) with severe IPSS (20-35) were defined as group 3. group 4 consisted of 117 healthy controls. Three groups and controls were compared about MS and its components. The diagnosis criteria of The Society of Endocrinology and Metabolism of Turkey were used in MS diagnosis. Also, BMI, lipid parameters, preprandial blood glucose, waist circumference, and blood pressure were used as MS parameters. RESULTS The average age of patients in group 1 was 69.8 ± 7.2; in group 2, 69.1 ± 7.4; 68.3 ± 7.1 in group 3 and 70.2 ± 7.2 in the control group. Metabolic syndrome was determined at 37 patients (50%) in group 1, 45 patients (46.5%) in group 2, 32 patients (48%) in group 3 and 52 patients (44.4%) in controls and no statistically significant correlation was detected between LUTS and MS in BPH (P = 0.113). In the comparison of the four groups in the point of MS parameters, no significant correlation was detected in the levels of total cholesterol (P = 0.337), fasting glucose (P = 0.291), BMI (P = 0.452), Low Density Lipoprotein (LDL, P = 0.069) and triglyceride (P = 0.307). CONCLUSIONS In our study, the evidence is not enough to support the hypothesis of the relevance between MS and LUTS. Wide-ranging, prospective and multicentric studies are needed to research the relevance between MS and LUTS in BPH.

Abstract
Background: To determine association between urine pH and OAB symptoms and to determine if urinary alkalization improves overactive bladder (OAB) symptoms. Methods: 659 patients with OAB were enrolled in this study between June 2012 and May 2014. 329 patients (group 1) were included in the final analysis. 201 adults were used as a control group (group 2). 24-hour urinary pH and the validated Turkish version of the OAB-V8 questionnaire were performed in patients. A 24-hour urine pH <6.2 was considered acidic urine. In the second part, a diet program was performed for 4 weeks in 30 participants. Urine pH values and OAB-V8 scoring results were recorded before the diet program and 2 and 4 weeks after the diet program. Results: Acidic urinary pH was determined in 61.4% of patients with OAB. There was a significant association between the presence of acidic urine and OAB. Also, the OAB-V8 scores of patients were significantly higher in patients with acidic urine than nonacidic urine. OAB-V8 scores of patients showed statistically significant improvement after diet therapy (17.87 ± 6.52 vs. 10.43 ± 7.17; p < 0.001). Conclusions: We found that acidic urinary pH was closely associated with OAB, and alkalization of urine improved lower urinary tract symptoms. We suggest that urinary pH should be considered as a parameter in treatment planning of patients with OAB.

Abstract
The Symphony study showed that at 1 year posttransplant, a regimen based on daclizumab induction, 2 g mycophenolate mofetil (MMF), low-dose tacrolimus and steroids resulted in better renal function and lower acute rejection and graft loss rates compared with three other regimens: two with low-doses of cyclosporine or sirolimus instead of tacrolimus and one with no induction and standard cyclosporine dosage. This is an observational follow-up for 2 additional years with the same endpoints as the core study. Overall, 958 patients participated in the follow-up. During the study, many patients changed their immunosuppressive regimen (e.g. switched from sirolimus to tacrolimus), but the vast majority (95%) remained on MMF. During the follow-up, renal function remained stable (mean change: -0.6 ml/min), and rates of death, graft loss and acute rejection were low (all about 1% per year). The MMF and low-dose tacrolimus arm continued to have the highest GFR (68.6 +/- 23.8 ml/min vs. 65.9 +/- 26.2 ml/min in the standard-dose cyclosporine, 64.0 +/- 23.1 ml/min in the low-dose cyclosporine and 65.3 +/- 26.2 ml/min in the low-dose sirolimus arm), but the difference with the other arms was not significant (p = 0.17 in an overall test and 0.077, 0.039 and 0.11, respectively, in pair-wise tests). The MMF and low-dose tacrolimus arm also had the highest graft survival rate, but with reduced differences between groups over time, and the least acute rejection rate. In the Symphony study, the largest ever prospective study in de novo kidney transplantation, over 3 years, daclizumab induction, MMF, steroids and low-dose tacrolimus proved highly efficacious, without the negative effects on renal function commonly reported for standard CNI regimens.

Abstract
Dialysis and kidney transplant patients display endothelial dysfunction. Previous studies concerning comparisons of endothelial function in dialysis and kidney transplant patients included subjects with cardiovascular risk factor(s) that alone may lead to endothelial dysfunction. In this study, we compared endothelial function between dialysis and transplant patients who did not show known cardiovascular risk factors that lead to endothelial dysfunction. We studied age- and gender-matched cohorts: 30 hemodialysis (HD), 30 peritoneal dialysis (PD), and 30 kidney transplant patients. We also included 20 age- and gender-matched healthy controls. We assessed the endothelial function of patients and controls by a noninvasive technique. Serum biochemistry profiles of patients were also similar to controls in terms of lipid profile and fasting blood glucose level. Although mean FMD% levels of HD and PD patients were similar (6.6% +/- 3.1% vs 6.8% +/- 3.0%, P > .05), the mean percent of flow-mediated endothelium-dependent dilatation (FMD%) level in transplant patients was higher than those in HD or PD patients (10.50% +/- 3.0% vs 6.6% +/- 3.1% and 6.8% +/- 3.0%, respectively; P < .01). In addition, the mean FMD% level in healthy controls was higher than those in HD, PD, and transplant patients (14.0% +/- 2.3% vs 6.6% +/- 3.1%, 6.8% +/- 3.0% and 10.50% +/- 3.0%; P < .01, respectively). In conclusion, endothelial functions in transplant patients were better than those in dialysis patients.

Abstract
BACKGROUND AND OBJECTIVE Previous studies in adults have demonstrated a clinically useful correlation between central venous pressure (CVP) and peripheral venous pressure (PVP). The current study prospectively compared CVP measurements from a central versus a peripheral catheter in kidney recipients during renal transplantation. METHODS With ethics committee approval and informed consent, 30 consecutive kidney recipients were included in the study. We excluded patients who had significant valvular disease or clinically apparent left ventricular failure. For each of 30 patients, CVP and PVP were measured on five different occasions. The pressure tubing of the transducer system was connected to the distal lumen of the central or to the peripheral venous catheter for measurements following induction of anesthesia, after induction, 1 hour after induction, reperfusion of the kidney, and the end of the operation, yielding 150 hemodynamic data points. Each hemodynamic measurement included heart rate, mean arterial pressure, mean CVP, and mean PVP determined at end-expiration. RESULTS The mean PVP was 13.5 +/- 1.8 mm Hg and the mean CVP was 11.0 +/- 1.5 mm Hg during surgery. The mean difference was 2.5 +/- 0.5 (P < .01). Repeated-measures analysis of variance indicated a highly significant relationship between PVP and CVP (P < .01) with a Pearson correlation coefficient of 0.97. CONCLUSION Under the conditions of this study, PVP showed a consistently high agreement with CVP in the perioperative period among patients without significant cardiac dysfunction.

Abstract
C-2 monitoring has been proposed as a more effective strategy than C-0 to predict the risk of acute rejection in the early stages posttransplantation. However, cyclosporine (CsA) is associated with posttransplant dyslipidemia. The aim of this retrospective study was to evaluate the correlations of C-0 and C-2 levels with atherogenic risk factors in the first 6 months versus after 6 months posttransplantation. We evaluated the data from 127 stable renal transplant recipients (89 males, 38 females) of mean age 38.10 +/- 12.79 years who received Neoral-based immunosuppression to investigate the relation of C-2 levels to serum lipid profile compared with C-0 values in the early and late posttransplantation periods. Receiver operating characteristic (ROC) analyses were performed to define a C-2 cutoff level that identified subjects with hypercholesterolemia, defined as a total cholesterol (TC) >200 mg/dL. There were significant positive correlations between both C-0 and C-2 levels and TC as well as the ratio of total cholesterol/HDL cholesterol (TC/HDL) in the late period. When the C-2 levels in the late posttransplantation period were stratified, serum TC concentrations showed statistically significant differences between the groups. Whole blood C-2 levels above 850 ng/mL were associated with increased serum TC concentrations; the C-2 cutoff level leading to hypercholesterolemia was 888 ng/mL. Maintenance immunosuppressive therapy under the proposed whole blood C-2 level of 888 ng/mL seemed to preserve graft function while preventing atherogenic risks for cardiovascular diseases in the late posttransplantation period.

Abstract
BACKGROUND To provide postoperative analgesia by spinal anesthesia, we compared the quality of analgesia and side effects of two doses of morphine added to ropivacaine in kidney donors. MATERIALS AND METHODS Thirty renal donors underwent nephrectomy under standard general anesthesia. After the operation, the patients were randomly allocated into two groups of intrathecal doses for spinal anesthesia: the 0.5 group (n = 15) received a total volume of 4 mL including 0.5 mg morphine, 10 mg ropivacaine, and 0.9% NaCl, and the 0.3 group (n = 15), a total volume of 4 mL including 0.3 mg morphine, 10 mg ropivacaine, and 0.9% NaCl. After extubation, an intravenous (IV) morphine protocol was initiated by a patient-controlled analgesia pump to provide sufficient spinal analgesia. RESULTS In the 0.3 group, the IV morphine consumption was significantly higher, namely, 14.60 +/- 7.57 times versus 4.60 +/- 10.14 times for the 0.5 group (P = .005). The total amount of morphine was 7.80 +/- 5.40 mg in the 0.5 group and 13.53 +/- 5.30 mg in the 0.3 group (P < .05). Postoperative side effects of nausea and vomiting were higher among the 0.3 group (P < .05). CONCLUSIONS In the 0.5 group, the quality of analgesia was better than in the 0.3 group. The need for IV morphine was less in the 0.5 group. Also, side effects like nausea and vomiting were less, so better analgesia in the postoperative period was obtained with the 0.5 mg morphine solution.

Abstract
To investigate disease-specific quality of life (QOL) in Turkish patients after successful kidney transplantation, the End-Stage Renal Disease Symptom Checklist Transplantation Module (ESRD-SCL-TM), a multidimensional questionnaire measuring disease-specific QOL, was translated and administered to a sample of successfully transplanted patients. Intercultural differences between Turkish and German patients as well as the influence of demographic (age, gender) and clinical (duration of graft function, living versus cadaver transplantation) data in the Turkish patients were evaluated by multivariate analyses of variance, and correlative techniques. The 152 investigated Turkish patients, including 106 (69.7%) men and 46 (30.3%) women, had a mean age of 34.8 years (SD = 10.8, range, 14 to 67 years). Time since successful kidney transplantation varied between 1 and 297 months (mean = 19.2 months; SD = 36.9). One hundred twelve patients (73.7%) received a kidney from a living donor, and 40 (26.3%) from a cadaver. The Turkish patients suffered statistically significantly more from disease-specific distress than the German patients (19% explanation of variance). They reported higher distress regarding four of six subscales. Turkish women suffered statistically significantly more from "Limited Physical Capacity," and "Side-effects of Corticosteroids" (10% explanation of variance) than men. The demonstrated higher disease-specific distress in successfully transplanted Turkish patients compared to the German samples may be the result of intercultural differences in reporting psychological and disease-specific distress. On the other hand, the higher distress of women compared to men is well known. Both results pointed out the necessity of psychological support.

Abstract
OBJECTIVES Mycophenolate mofetil (MMF) has become more widely prescribed in recent years, but its adverse effects on the gastrointestinal system and bone marrow restrict its use in certain settings. The aim of this study was to compare the demographic features and clinical data for 173 renal transplant recipients who received tacrolimus (TAC) plus 1 g/d MMF (group I, n = 112) versus TAC plus 2 g/d MMF (group II, n = 61 patients) over a 2-year period. Each patient received similar TAC doses. METHODS We compared demographic data and clinical data for each case: acute rejection (AR) episodes, chronic rejection (CR) episodes, death, graft loss, development of posttransplantation diabetes mellitus (PTDM), and posttransplantation hypertension rates. RESULTS Demographic features were similar. There were also no significant differences between groups I and II with respect to number of AR episodes (17/112 vs 12/61, respectively), number of CR episodes (4/112 vs 1/61, respectively), PTDM, and hypertension rate (P > .05). Kaplan-Meier survival analysis revealed 2-year graft survival rates of 94% in group I versus 83% in group II. The corresponding 2-year patient survival rates were 100% in group I versus 91% in group II. The graft survival and patient survival rates in group I were significantly higher than those in group II (log-rank 0.005 and 0.001, respectively). CONCLUSIONS The 2-year graft and patient survival rates for the renal transplant recipients in this study suggest that the combination of a full TAC dose with 1 g/d MMF is a better choice than 2 g/d MMF.

Abstract
INTRODUCTION One treatment option for patients with type 1 diabetes mellitus with end-stage nephropathy is combined pancreas-kidney transplantation, which can be performed either simultaneously (SPK) or following kidney transplantation (PAK). PATIENTS AND METHODS Between February 2003 and November 2004, 14 patients, including 10 males and 4 females of overall mean age of 31.3 +/- 6.1 years (range, 23-44 years), presented with end-stage renal disease secondary to type 1 diabetes mellitus. Five patients (35.7%) received SPK; 7 patients (50%) received PAK; and 2 patients (14.3%) received simultaneous pancreas and living-related kidney (SPLK) transplantations. RESULTS Two among 14 pancreas grafts were lost in the early postoperative period secondary to venous thrombosis despite anticoagulation including 1 with poor portal drainage. Insulin therapy was reinitiated in 1 patient after a second rejection episode in the seventh postoperative month. By the ninth median follow-up month (range, 1-21 months), all kidney grafts were functioning. CONCLUSION Our single-center short-term experience with 14 consecutive kidney-pancreas transplantations suggests that while the pancreas transplant is effective and safe to reestablish normoglycemia, this transplant creates additional surgical and immunosuppressive stresses on the patient.

Abstract
Lack of expansion of the deceased donor supply has resulted in a severe shortage of organs worldwide. Spousal donors are one possible alternative organ source for patients on the kidney transplant waiting list. Despite human lymphocyte antigen (HLA) matching between recipients and unrelated donors being poor, the reported survival rates for these grafts, including spouses, are comparable to those for grafts from living related donors and higher than those for deceased donor kidneys. In 2000, our renal transplantation program began accepting living donor-recipient pairs with one or zero HLA matches. The purpose of this study was to assess this policy for accepting living unrelated donors. The 3-year graft survival rates for the transplants from living unrelated donors were similar to that for transplants from living related donors (log-rank = 0.078). The number of HLA mismatches did not significantly influence the survival rates for either of these groups of living donor transplants. Multivariate analysis revealed that dialysis duration (P = .057) and recipient age (P = .066) negatively influenced patient survival in living donor kidney transplantation. The graft and patient survival rates for the donor transplantations were higher than those for deceased donor transplantations. In light of these findings and considering the increasing problem of organ shortage, we conclude that living unrelated kidney transplantation should be performed, with strict guidelines. Spousal donation is the most favorable form of living unrelated renal transplantation.
