Assessment of meatal stenosis in neonates undergoing circumcision using Plastibell Device with two different techniques

Purpose

It was intended to compare meatal stenosis (MS) as a late complication of neonatal circumcision by using two different methods of Plastibell Device circumcision.

Materials and methods

A total of 2,307 healthy term newborns (6–36 hours) who were born between 2007 and 2009 in Niknafs Medical Center of Rafsanjan, Iran, were simply randomized into two groups in a controlled, nonblinded clinical trial. In group A (1,102 neonates), the frenulum was maintained intact without any manipulation, and in group B (1,205 neonates) frenular hemostasis was performed in all cases by thermal cautery. MS was assessed by follow-up visits that were made for all cases at the 24–72 hours, 60th day, 12th month, and 16th month after circumcision.

Results

At 2 months follow-up visit, the rate of MS in group A was 4.9% (54) and in group B was 5.9% (71), which was not statistically significant. After 12 months, MS in group A was 8.5% (94) and in group B was 13.7% (165), which was statistically significant (P<0.001). At 16 months after circumcision, in the frenulum intact group, MS was 13.8% (152) and in the cautery group, it was 18.9% (228), which was compatible with significant difference (P=0.001).

Conclusion

Our experience with large group of cases revealed that neonatal circumcision by using Plastibell Device with intact frenulum technique decreases the rate of delayed MS.

Does intraperitoneal injection of propofol prior to detorsion improve testes weight and histopathological findings in a rat model?

Objectives

To determine the long-term preventive effects of intraperitoneal propofol on testicular ischemia–reperfusion injury in a rat model.

Materials and methods

Forty adult male albino Wistar rats were divided randomly into the following four groups according to the planned treatment (n=10 per group): group I, control; group II, sham-operated; group III, torsion/detorsion (T/D); and group IV, T/D plus propofol. Testicular ischemia was achieved by twisting the left testis 720° clockwise (ie, applying torsion) for 1 h. In the T/D plus propofol group (group IV), 50 mg/kg propofol was administered intraperitoneally 30 minutes before detorsion. Ipsilateral orchiectomy was performed under general anesthesia to determine the mean testicular weight and to enable histopathological examination of the testes using Johnsen’s mean testicular biopsy score 30 days after the surgical procedure in all groups.

Results

The testicular weights in groups I, II, III, and IV were 1.65±0.32, 1.59±0.33, 1.11±0.56, and 1.08±0.50 g (mean ± SD), respectively. Testicular weight was significantly lower in the T/D groups (III and IV) than in both the control and sham-operated groups (I and II), but there was no improvement in testicular weight as a result of propofol administration. Similarly, Johnsen’s mean testicular biopsy score was lower in groups III and IV than in groups I and II, but no positive effect was conferred by the administration of propofol in group IV.

Conclusion

The use of propofol in the treatment of testicular ischemia–reperfusion injury caused by testis torsion has no significant long-term therapeutic potential.

Ewing sarcoma/primitive neuroectodermal tumor of the kidney: A report of three cases

•

Ewing sarcoma/primitive neuroectodermal tumor of the kidney (ES/PNET) is a member of Ewing’s sarcoma family, occurring in young adults.

•

The clinical course and prognosis of ES/PNET are different from renal cell carcinoma (RCC).

•

For definite diagnosis, in addition to cytogenetic analysis; other techniques may be needed; such as fluorescent in situ hybridization (FISH), reverse transcriptase-polymerase chain reaction (RT-PCR) of the t (11; 22) translocation [1].

Introduction

Ewing sarcoma/Primitive neuroectodermal tumor of the kidney (ES/PNET) is a member of Ewing’s sarcoma family, occurring in young adults and has aggressive clinical behavior and poor prognosis. However, its discrimination from the renal cell carcinoma (RCC) is very difficult preoperatively. We present three cases of this rare disease that were managed in two academic centers.

Presentation of cases

Herein we report three cases of ES/PNET of the kidney, 2 young men complaining of right flank pain and gross hematuria and one young woman complaining of left subcostal pain. In two cases computerized tomography (CT) scan revealed huge renal masses which were excised by radical nephrectomy. Microscopic examination of the nephrectomy specimen showed primitive neuroectodermal tumor features which confirmed by immunohistochemistry (IHC).

Two of 3 patients were treated with adjuvant chemotherapy and the third patient with neoadjuvant chemotherapy. They were symptom-free until now.

Discussion

The clinical course and prognosis of ES/PNET are different from renal cell carcinoma (RCC) and definite pathologic diagnosis is necessary for optimum treatment. For definite diagnosis, in addition to cytogenetic analysis; other techniques may be needed; such as fluorescent in situ hybridization (FISH), reverse transcriptase-polymerase chain reaction (RT-PCR) of the t (11; 22) translocation or the EWS-FLI and related gene fusions [1].

Conclusion

Up to our knowledge and search in English literature, this is the first case series that was reported from a major referral center from our country, Iran.

Evaluation of orchiopexy practice patterns in patients with cryptorchidism: a single-centre study

OBJECTIVE

A retrospective study was conducted to determine the age at which orchiopexy was performed, and the laterality and anatomic location of undescended testes (UDTs) or non-palpable testes (NPTs). All documented orchiopexies performed in a large referral centre of Qom province, Qom, Iran during a 5 year period were evaluated.

MATERIALS AND METHODS

A total of 324 patients admitted for surgical correction of cryptorchidism from 2005 to 2009 were eligible for inclusion in our study. The patients were divided into two groups: group A paediatric orchiopexy, and group B adult orchiopexy.

RESULTS

There were 252 paediatric patients (78%), with a mean age of 4.44 years, and 72 adult patients (22%). Forty-three patients (17%) were under 2 years of age and 59 patients (23.5%) were between 2 and 3 years. Right-side involvement was seen in 126 patients (50%), left-side in 91 patients (36%), and bilateral involvement in 35 patients (14%). Unilateral cryptorchidism was seen in 217 patients (85%). Regarding the anatomical location of the testes in unilateral cryptorchidism, superficial inguinal testis was seen in 117 patients (54%).

CONCLUSION

The higher age of orchiopexies determined from this study compared with the recommended age for surgery, indicates that active interventions are necessary with public health education programs for patients, parents, midwives and general practitioners.

Evaluation of acute scrotum in our consecutive operated cases: a one-center study

Purpose

The purpose of the present study was to evaluate the clinical history, demographic data, surgical exploration findings, and final diagnoses in all young males presenting with acute scrotum to our center.

Materials and methods

This was a descriptive–retrospective study in which all consecutive cases of acute scrotum treated in our department from March 2008 to March 2012 were evaluated.

Results

A total of 116 cases were included in the study. Out of these cases, 100 cases underwent surgical exploration, and the remaining 16 cases were managed conservatively. Our eligible cases were divided into three groups: the testicular torsion (TT) group (68%); the torsion of the appendix testis (AT) group (20%); and the epididymo-orchitis (EO) group (9%). Testicular preservation was achieved in 39 cases of the TT group, while due to delayed referral, orchiectomy was performed in 29 cases. Thus, our testicular salvage rate was 57.5% and missed testicular torsion rate was 42.5%.

Conclusion

It was observed that our testicular salvage rate was lower than the expected figures published in the literature. This is may be attributed to different causes, including delayed referral or presentation of acute scrotum cases, inadequate knowledge of the general practitioners working in emergency departments, or poor knowledge of parents.

Evaluation of epidemiology, concomitant urethral disruption and seasonal variation of penile fracture: A report of 86 cases

INTRODUCTION

Penile fracture (PF) is a well-recognized clinical entity and is often deemed a urological emergency. It is not uncommon in our region. The main objective of this study is to describe the clinical characteristics of patients diagnosed with penile fracture in the Qom Province, Iran. We evaluate surgical treatment, concomitant urethral disruption and its seasonal variation.

METHODS

This is a descriptive retrospective study, reviewing all the medical records of patients admitted with penile fracture from 2003 to 2012 at Kamkar Hospital of Qom, Iran. It takes into account variables related to the urological history, etiology, diagnosis and its surgical treatment. The epidemiologic data, marriage status and the seasonal variation were evaluated. In total, 86 patients, aged between 17 and 62, with PF were hospitalized in our centre. The average age of patients was 36.74 years. All operated cases were followed 3 months and 6 months after surgery.

RESULTS

Of the 86 patients, 34 (68%) were the ages of 20 and 40. In terms of marital status, 56 (65%) were married and 30 (35%) were single at the time of presentation. Twenty-six patients (30.2%) had episodes related to intercourse and 48 patients (56%) to manual habitual trauma; the remaining 12 patients had a direct blow to an erect penis or rolled/fell off a bed. Patients presented with swelling, pain and a popping or cracking sound in the penis. The diagnosis was made using history and physical examination in all patients. Unilateral corporeal ruptures were present in 80 (93%) and bilateral in 2 cases (2.32%). Surgical repair was performed with a circumferential sub-coronal degloving incision in 82 cases (95.35%). There were seasonal variations: 22 cases in spring; 25 in summer; 17 in autumn; 22 in winter. Patients had an average postoperative hospital stay of 1 day.

CONCLUSION

Habitual manual trauma was the most common cause of PF in our study. Immediate surgical intervention has low morbidity, short hospital stay and rapid functional recovery. In the case of urethrorhagia, concomitant urethral injury should be evaluated. On the basis of our study, PF may have seasonal variation.

Obstructive uropathy due to prolapsed lower ureters and bladder in patients with severe procidentia: A report of two cases

INTRODUCTION

Pelvic organ prolape is not uncommon in multi-parous or elderly women. It is one of the rare but important causes of obstructive uropathy. Herein, we report two cases of severe procidentia that were referred with obstructive uropathy due to prolapsed bladder and ureters.

PRESENTATION OF CASE

The first case was a 78-year-old woman, with severe pelvic organ prolape and secondary bilateral hydroureteronephrosis and post-renal failure. She was treated successfully by bilateral nephrostomy insertion and then pessary insertion. The second case was a 75-year-old woman who referred with the same presentation, but treated surgically with burch colposuspention and synchronous bilateral ureteral stent insertion.

DISCUSSION

Pelvic organ prolapse is not uncommon in old women. In addition to physical problems of procidentia, it may cause acute renal failure (ARF), chronic renal failure (CRF), and finally end stage renal disease (ESRD) if undiagnosed.

CONCLUSION

In every aged female case with obstructive uropathy and/or bilateral hydroureteronephrosis with unknown causes, gynecologic examination should be performed for early detection of possible pelvic organ prolapse. Appropriate management is necessary to prevent renal failure from uterine prolapse (UP).

Primary obstructive megaureter with a giant lower ureteral stone synchronous with ipsilateral staghorn kidney

INTRODUCTION

Primary obstructive megaureter (POM) is uncommon in adults. Urolithiasis formation may uncover the underlying congenital abnormally of these patients.

PRESENTATION OF CASE

Herein, we present a 20-year-old man who was admitted with synchronous left renal staghorn and a lower giant ureteral stone. Radiologic evaluations revealed that POM is the underlying cause of the uncommon occurrence of synchronous left reno-ureteral stone formation.

DISCUSSION

Urinary tract stones are not uncommon in the POM. Although synchronous renal-ureteral unit stones are less common but staghorn-ureteral stones complex are very rare. In such conditions full radiologic work-up is recommended. Based on our literature review, this is the first reported case of staghorn-ureteral stones complex in the setting of adult POM.

CONCLUSION

In every case with dilated ureter concomitant with ureteral stone or renal stone, the POM should be included in the differential diagnosis.

Malignant abdominal paraganglioma presenting as a giant intra-peritoneal mass

INTRODUCTION

Paraganglioma is a malignant tumor that arises from the extra adrenal paraganglionic cells of the sympathetic or parasympathetic systems. Herein, we present a case of abdominal mass of unknown histology that underwent a very difficult surgical mass resection. Its final histologic diagnosis was non-functional paraganglioma that was presented as a huge intra-peritoneal mass.

PRESENTATION OF CASE

The patient was a 55-year-old Iranian lady who referred to our center with a giant abdominal mass. Fine needle aspiration (FNA) biopsy showed undifferentiated carcinoma. After laparotomy for mass resection pathology evaluation revealed; malignant paraganglioma, non-metastatic type. Further post-operative patients evaluations showed that the tumor was sporadic in nature and the subsequent patient's natural history was uneventful.

DISCUSSION

Pathologic evaluations have key roles in the exact diagnosis of abdominal masses with unidentified sources. For the paragangliomas, all of them should be regarded malignant until proved otherwise. However, combined use of biochemical markers, immunohistochemical techniques (IHC), and genetic analysis have key roles in the diagnosis and treatment of paragangliomas. Additionally, surgical removal is the proved curative way of paraganglioma treatment.

CONCLUSION

Asymptomatic intra-peritoneal paraganglioma is very rare, especially its malignant variety. This case emphasizes that full pathologic investigation would reveal the exact nature of idiopathic abdominal masses, especially in the state of absence of typical clinical and para-clinical symptoms.

Transperitoneal laparoscopic heminephrectomy in duplex kidneys: a one centre experience

PURPOSE

The standard treatment for a duplex kidney with poorly functioning upper pole moiety is ipsilateral upper pole heminephrectomy. This procedure is usually performed by open surgery, but with recent developments in techniques of uro-laparoscopy, it can be done with it, safely. In this study we evaluated the results and safety of laparoscopic heminephrectomy in our consecutive cases.

MATERIALS AND METHODS

From February 2001 to May 2007 fourteen unilateral laparoscopic heminephrectomy were performed in our center. Patients' characteristics, presenting symptoms, operative time, and blood loss, early and late complications were all collected retrospectively. Using pre-operative ultrasonography, intravenous pyelography (IVP) and CT scanning, unilateral upper pole hydronephrosis was detected in all cases. By DMSA isotope scan hypofunctioning of ipsilateral moieties was detected in all cases.

RESULTS

Mean operative time was 203±80 minutes. No major intra-operative or early complications were identified. Mean hospital stay was 4.1 days. On mean follow-up of 32 months no disturbing symptoms or episodes of urinary tract infections (UTIs) were detected. Atrophic kidney was detected in one case in post-operative IVP.

CONCLUSION

Laparoscopic heminephrectomy is a valuable minimal invasive procedure that can be performed safely in experienced hands without any important complication. Perfect renal pedicles vascular system manipulation is important for the preservation of renal function post-operatively.

Chronic headache as the first symptom of an undiagnosed renal cell carcinoma

Renal cell carcinoma (RCC) is an uncommon tumor that rarely metastasizes primarily to the brain. Brain metastases are commonly observed in patients with metastatic RCC, with a reported incidence of 2–17%. The prognosis of brain metastatic RCC is poor. In this carcinoma type, the source is commonly evident. We report a case of a patient with undiagnosed incidental RCC, who presented chronic headache as the first manifestation.

Evaluation of biochemical urinary stone composition and its relationship to tap water hardness in Qom province, central Iran

Purpose

The aim of this study was to evaluate the biochemical stone composition in general population of Qom province, central Iran, and its relationship with high tap water hardness.

Materials and methods

In a prospective study, from March 2008 to July 2011, biochemical analysis of urinary stones in patients living in Qom province for at least 5 years was performed. Stones were retrieved by spontaneous passage, endoscopic or open surgery, and after extracorporeal shockwave lithotripsy. Demographic findings and the drinking water supply of patients were evaluated and compared with biochemical stone analysis.

Results

Stone analysis was performed in 255 patients. The most dominant composition of urinary stones was calcium oxalate (73%), followed by uric acid (24%), ammonium urate (2%), and cystine (1%). The peak incidence of urinary stone was in patients in their forties. Overall male to female ratio was 4.93:1.

Conclusion

The dominant stone composition in inhabitants of central Iran, where tap water hardness is high, was calcium oxalate stones. On the basis of this study, biochemical urinary stone composition of Qom does not differ from other regions of Iran with lower water hardness.

Transverse testicular ectopia, a case report and review of literature

Crossed testicular ectopia (CTE)/transverse testicular ectopia (TTE) is a rare but well known congenital anomaly, in which both gonads migrate toward the same hemiscrotum. It is usually associated with other abnormalities such as persistent Mullerian duct syndrome, true hermaphroditism, inguinal hernia, hypospadias, pseudohermaphroditism, and scrotal anomalies. About 100 cases of transverse testicular ectopia have been reported in published studies. We report a case of transverse testicular ectopia in an 8-month-old boy who presented with right inguinal hernia and nonpalpable left testis. On exploration, both testes were present in the right inguinal region. Bilateral orchiopexy was performed by crossing the left testis in the extra-peritoneal space and ipsilateral scrotal orchiopexy. The diagnosis could not be made preoperatively in most of reported cases.

Evaluation of prostate cancer prevalence in Iranian male population with increased PSA level, a one center experience

PURPOSE

This study was conducted to evaluate the incidence of prostate cancer (PCa) in Iranian male patients with increased prostate-specific antigen (PSA), and normal or abnormal digital rectal examination (DRE) that underwent prostate biopsy.

MATERIALS AND METHODS

From March 2006 to April 2009, a total of 346 consecutive males suspected of having PCa due to increased PSA levels underwent transrectal ultrasonography (TRUS)-guided sextant biopsy of the prostate. The total PSA (tPSA), demographic data, incidence of PCa, benign prostate hyperplasia (BPH), and prostatitis were assessed.

RESULTS

The patients were divided into two groups according to their PSA values (group A serum tPSA level, 4-10 ng/mL; group B serum tPSA level, 10.1-20.0 ng/mL). Of the 346 biopsied cases, 193 cases (56%) had PCa, 80 cases (23%) had BPH, and 73 cases (21%) had prostatitis. The mean PSA and the age of the carcinoma group were significantly higher than those of the benign group (P < 0.01). The biopsy results were grouped as PCa, BPH, and prostatitis. Incidence of PCa for group A and group B cases were 115 cases (51%), and 78 cases (65%), respectively. In the case of PCa, BPH, and prostatitis, the mean PSAs were 10.02 ng/mL, 8.76 ng/mL, and 8.41 ng/mL, respectively (P < 0.40).

CONCLUSION

TRUS-guided prostate biopsy and interpretation by a skilled team is highly recommended for early detection of PCa or its ruling-out. It seems that a PSA cutoff value of 4 ng/mL may be applied to the Iranian population. Although the chance of PCa is high in the PSA levels of 4-10 ng/mL, the combination of some data, like age and prostate volume, can decrease the rate of unnecessary prostate biopsies. We recommend prostate biopsy when PSA and/or DRE is elevated in symptomatic patients with obstructive and/or irritative lower urinary tract symptoms (LUTS) such as dysuria, frequency, or nocturia. Due to the very high incidence of PCa in the patients with PSA greater than 10 ng/mL, TRUS-guided biopsy is indicated, whatever the findings on DRE and/or LUTS, since the PCa detection rate is high.

Mathieu repair of distal and midshaft hypospadias: risks and benefits of foreskin reconstruction versus circumcision

Background

The purpose of this study was to compare the risks and benefits of Mathieu repair of hypospadias with or without circumcision in consecutive operated cases.

Methods

Eighty-six children with midshaft or distal hypospadias were randomly divided into two groups and underwent circumcision (Group A) or preputial reconstruction (Group B) during hypospadias repair. Postoperative complications, outcomes, and parental satisfaction were assessed for circumcised and uncircumcised patients. All patients with midshaft or distal hypospadias with or without minimal chordee were included.

Results

No statistically significant differences in urethral complications were found between the two groups. Meatal stenosis occurred in one case in Group A and one case in Group B. Fistulae occurred in five cases in Group A and six cases in Group B. Urethral dehiscence occurred in no case in either group. No case of phimosis was seen in Group B. After a mean follow-up of 6 months, all parents of Group A cases stated that they were satisfied with the circumcision for religious and/or social reasons, but no parents of Group B cases were satisfied with preputioplasty (P ≤ 0.05). No case of hypospadias repair failure was seen in our operated cases. Finally, no cases in Group B required redo hypospadias surgery.

Conclusion

Mathieu repair with synchronous circumcision is feasible in all patients with distal or midshaft hypospadias with or without minimal chordee, and should be considered in accordance with surgeon preference. In the case of prepuce preservation, parents should be informed that there is a benefit of tissue banking for probable redo hypospadias repair but with an increased risk of complications and a need for another procedure, ie, circumcision.

Evaluation of epidemiology, safety, and complications of male circumcision using conventional dissection surgery: experience at one center

BACKGROUND

Circumcision can be performed for a variety of techniques, including conventional dissection surgery or a Plastibell device, and has religious, ritual, or medical roots. In countries like Iran, circumcision is done purely on religious grounds. In this study, we outline 390 cases in our practice and describe the epidemiology, indications, surgical technique used, and the early complications.

MATERIALS AND METHODS

In this retrospective study, the charts for 390 circumcision cases were analyzed for the period March 2005 to August 2010. We reviewed all cases, noting age, indication, type of anesthesia used, technique, cosmetic appearance, and any potential early complications. All cases were followed up 1-4 weeks postoperatively and their notes were evaluated.

RESULTS

The age of children who underwent circumcision ranged from 3 weeks to 14 years, with a mean age of 4.25 years. The most common age for circumcision was 4-5 years (14.6%), and the least common age was 11-12 years (1.5%). In 372 cases (95%), the parents had opted for the procedure for religious reasons, and in 18 cases (5%), there was a medical indication, including phimosis (11 cases, 3%), urinary tract infection (5 cases, 1.2%), and balanoposthitis (2 cases, 0.8%). No major early complications were found in our series. Cosmetic appearance was satisfactory in all cases by 4 weeks after the operation.

CONCLUSION

Circumcision was performed for religious reasons in our cases, although medical indications sometimes modified the timing of the procedure. Conventional dissection surgery for circumcision was safe, effective, and without any major complications.

Genitourinary system trauma after 2003 Bam earthquake in Kerman, Iran

Background:

Natural disasters, especially earthquakes, result in many health problems all over the world, of which urological injuries should not be underestimated. Car accidents and falling from a height are the most common causes of genitourinary system injury. The lack of specific data in the literature regarding the outcome of earthquake-related genitourinary system trauma prompted us to undertake this study.

Methods:

We retrospectively evaluated the genitourinary system injury in patients who had survived the Bam earthquake. In this study, all patients admitted to two main back-up hospitals of Kerman were included. Of 256 patients who had been referred to Kerman hospitals, 28 cases were found to have urologic damage on physical examination, intravenous pyelography, abdominopelvic X-ray, and ultrasonography.

Results:

Of 28 patients with urologic damage, 22 (78.5%) were male and six (21.5%) were female. Their age ranged from 18 to 65 years. The injures included urethral disruption in 21 cases (75.5%), vesicovaginal fistula in four cases (14%), kidney rupture in two cases (7%) and bladder neck disruption accompanied with total right ureteral disruption and vesicovaginal fistula in a female patient (3.5%).

Conclusion:

We have evaluated the incidence of genitourinary injuries after an earthquake disaster for the first time. The most and least common urologic injury in our patients was urethral disruption and ureteral injury, respectively.

Comparison between imipramine and imipramine combined with pseudoephedrine in 5-12-year-old children with uncomplicated enuresis: a double-blind clinical trial

OBJECTIVE

Monosymptomatic nocturnal enuresis is a common entity, with a prevalence of 10% at the age of 7 years. For its primary treatment, we compared the effect of combination medical therapy (imipramine with pseudoephedrine) with imipramine alone.

MATERIALS AND METHODS

In this one-center prospective double-blind clinical trial, 100 school-age children (age range 5-12 years) were enrolled. They were divided into two groups, comparable in terms of age and other demographic factors: (A) adjusted doses of a combination of imipramine with pseudoephedrine, and (B) imipramine with placebo were administered. Improvement was defined as less than 2 wet nights per week.

RESULTS

Four weeks after drug withdrawal, the response rate was 74% in group A in comparison to 52% in group B, this difference being statistically significant. There was a recurrence of enuresis in both groups during the 4 weeks after treatment was discontinued (10% increase in group A and 8% increase in group B).

CONCLUSION

The additive pharmacologic effects of imipramine with pseudoephedrine for the treatment of monosymptomatic nocturnal enuresis in children were well tolerated, and gave significantly faster results than single drug therapy using imipramine. The moderate-to-high recurrence rate following discontinuation of medical treatment indicates the need for a longer term study involving more cases.

Urologist-operated ultrasound and its use in urological outpatient clinics

INTRODUCTION

Ultrasonograghy plays an important role in the evaluation of urinary tract disorders in cases of medical or surgical renal disorders, because of its lower cost, availability, and lack of ionizing radiation and because with it there is no need for contrast material injection or ingestion. It needs no intervention or preparation and specifically can differentiate between the multiple causes of flank pain. Urologist-operated sonography is a quick, cost-effective, and time-saving modality for both the physician and patient for obtaining first or final diagnosis. Based on its results, patients can be selected for appropriate management and further assessment.

MATERIALS AND METHODS

The efficacy of ultrasound examination by a trained urologist in the differentiation of urological emergencies admitted in a district private clinic was studied. Between April 2008 and April 2010, a total of 724 patients (1448 renal units) had renal ultrasound performed by a trained urologist on acute admission. The sonographic findings were compared with subsequent definitive radiological investigations performed as needed, such as KUB (kidney, ureter, bladder) or IVP (intravenous pyelogram). Patient satisfaction and permission for ultrasonography were evaluated by oral consent. Loin pain was the presenting symptom in 45% of the patients (n = 326 cases).

RESULTS

Diagnosis was achieved in 96% of patients. Further evaluations were requested as needed in suspicious cases. If any hydronephrosis was detected and patients' history and/or complaints were suggestive of renal or ureteral stones, an outpatient KUB was requested. For more complex situations, IVP was the next option. Abnormal findings were recorded in 184 cases (25.5%). Mild to moderate unilateral hydronephrosis with or without hydronephrosis was the most common finding observed sonographically. The sensitivity of our ultrasonography evaluation was 99.7%.

CONCLUSION

Office urologist-operated sonograghy may supplement the information available through routine history, physical examination, and laboratory studies. Our study shows that urological trainees can use ultrasound with high levels of accuracy, thereby improving patient management with a high level of patient satisfaction.

Percutaneous nephrolithotomy complications in 671 consecutive patients: a single-center experience

PURPOSE

To evaluate major and minor complications of percutaneous nephrolithotomy (PCNL) and their management in our consecutive cases.

MATERIALS AND METHODS

We reviewed medical records of 671 patients who had undergone PCNL in our center from March 2000 to March 2006. The demographic data, stone parameters, PCNL complications, and stone-free rate were evaluated. Multiple parameters were evaluated for their association with PCNL complications using Chi-Square test.

RESULTS

Complications occurred in 203 (30.3%) patients; renal parenchymal injury in 103 (15.4%), peri-operative bleeding in 42 (6.3%), late bleeding in 6 (0.9%), renal collecting ducts injury in 35 (5.2%), fever in 7 (1.0%), colon perforation in 2 (0.3%), major vessels injury in 3 (0.4%), pneumothorax in 3 (0.4%), and hemothorax in 2 (0.3%) subjects. Mortality occurred in 1 patient with colon perforation (0.15%).

CONCLUSION

Percutaneous nephrolithotomy has low complication rate in experienced hands.

Renal Cell Carcinoma with Simultaneous Bilateral Adrenal Metastasis: Ipsilateral Radical Nephrectomy with Contralateral Adrenal Preservation

Although renal cell carcinoma (RCC) can metastasize to almost every organ, the most common metastatic sites are the lungs, abdomen, bones and brain. We present a rare case of a 72-year-old male with a large left RCC with simultaneous bilateral adrenal metastasis. In the process of surgical treatment, he underwent left radical nephrectomy with ipsilateral adrenalectomy. Due to the poor general condition of the patient, and also to prevent adrenal insufficiency, the right adrenal mass was preserved, without imposing any hazard to the patient. Systemic immunotherapy was initiated and the patient is still alive 1 year after surgery.

Severe Dyspnea due to Pulmonary Metastasis of Renal Cell Carcinoma: Is Cytoreductive Surgery of Value?

Here, we present a case in which cytoreductive surgery, like left radical nephrectomy, was effective in the treatment of pulmonary metastases and para-aortic metastases from renal cell carcinoma. A 28-year-old man underwent left radical nephrectomy with pulmonary metastasectomy for the diagnosis of metastatic left renal cell carcinoma. The histologic diagnosis was clear cell carcinoma G2, pT3N1M1. He subsequently underwent i.m. administration of IFN-α, 5 million units per day for 30 days. The nasal oxygen mask was weaned gradually, and the chest tube was removable due to cessation of the continuous production of pleural fluid. The patient was well until one year after operation.

A Huge Renal Cell Carcinoma, Nine Years after Its Primary Diagnosis and Obligate Observation

The clinical diagnosis of renal cell carcinoma (RCC) is radiographic. Effective imaging of the kidneys can be achieved by ultrasound, CT or MRI [Chawla et al.: J Urol 2006;175:425–431]. Solid lesions detected by ultrasound and those showing enhancement on cross-sectional imaging are considered malignant until proven otherwise. The standard of care for clinically localized RCC remains surgical resection due to the favorable prognosis associated with surgery and the relative ineffectiveness of systemic therapy. Since patients with localized RCC are often symptom-free, they sometimes refuse to receive surgical treatment or are left untreated based on a diagnosis of benign lesions. There are also cases where an RCC is relatively large and causes symptoms but is not treated surgically because of complications and other reasons. We report a 54-year-old male who underwent a difficult radical nephrectomy 9 years after the primary RCC malignancy diagnosis.

One-suture, 1-knot technique in renal vascular transplant

OBJECTIVES

We describe the results of our 1-suture, 1-knot technique for vascular anastomosis in renal transplant. This technique can be used for both of the arterial and venous anastomoses.

MATERIALS AND METHODS

Between May 2006 and June 2008, a total of 386 renal transplants were done in our center, using a 1-suture, 1-knot technique. Intraoperative data including the warm and cold ischemic time, arterial and venous anastomotic time, and any early and late postoperative complications in the follow-up were recorded.

RESULTS

Mean age of recipients was 37 years. Mean kidney warm and cold ischemia time was 4.8 and 26.2 minutes. Mean arterial and venous anastomotic time was 5.1 and 7.2 minutes. No vascular complications were seen in the early postoperative period. Delayed graft function was diagnosed in 36 patients, but a renal scan showed good perfusion of the allografts of these cases. In the mean follow-up of 18.5 months, we did not encounter any case of renal artery thrombosis or any suspected arterial stenosis.

CONCLUSIONS

The 1-suture, 1-knot technique is a safe, rapid, and easy method for arterial and venous anastomosis of the renal allograft with low complication rates. It is especially valuable in obese patients and recipients with deep iliac fossa.

A Huge Ovarian Cyst in a Middle-Aged Iranian Female

A 38-year-old Iranian woman was found to have a huge ovarian cystic mass. Her presenting symptom was vague abdominal pain and severe abdominal distention. She underwent laparotomy and after surgical removal, the mass was found to be mucinous cystadenoma on histology.

Primary Lymphoma of the Kidney in an Adult Male - The First Reported Case from Iran

We report a case of primary renal lymphoma in a 48-year-old man. He was admitted with a large homogenous right renal mass that was revealed by computed tomography scan of the abdomen and pelvis. The patient underwent transperitoneal right radical nephrectomy. Pathologic diagnosis was in favor of primary renal lymphoma.

Mixed epithelial and stromal tumor of the kidney or adult mesoblastic nephroma: an update

PURPOSE

Our aim was to review the spectrum of usual and unusual clinical and morphologic findings observed in mixed epithelial and stromal tumor of the kidney (MEST).

MATERIALS AND METHODS

On the basis of MEDLINE database searches, we assessed all aspects of MEST or adult mesoblastic nephroma since the first report in 1997 till the end of 2009.

RESULTS

Mixed epithelial and stromal tumor is a relatively rare and distinct neoplasm of the kidney that should be distinguished from other renal neoplasms. Although the overall prognosis is favorable, recurrence and malignant transformation of MEST can occur

CONCLUSION

It is difficult to distinguish benign or malignant nature on imaging studies.

A modified technique of simple suprapubic prostatectomy: no bladder drainage and no bladder neck or hemostatic sutures

INTRODUCTION

Open prostatectomy is the conventional surgical treatment of benign prostatic hyperplasia. The major early complication of this procedure is bleeding. We introduce a technique of prostatectomy in order to prevent significant bleeding, reduce morbidity, and shorten convalescence and hospital stay periods.

MATERIALS AND METHODS

We enrolled 202 consecutive patients diagnosed with benign prostatic hyperplasia who were candidates for open prostatectomy. The operation was performed by one surgeon within 6 years using a modified technique of simple suprapubic prostatectomy (no bladder drainage and no bladder neck suture). Clot retention episodes, hemoglobin decrease, urethral catheterization time, and hospital stay were evaluated postoperatively. The patients were followed up for 1 to 2 years.

RESULTS

The mean operative time was 18 minutes (range, 14 to 28 minutes) with an estimated mean intra-operative blood loss of 120 mL. The mean hospital stay was 3 days (range, 2 to 4 days). The median urethral catheterization time was 5 days. No intra-operative complication or mortality was noted. Return to baseline urinary function and subjective continence at 3 months were 100% and 99%, respectively. Only in 1 patient (0.4%), bladder neck contracture was detected 3 months after the operation.

CONCLUSION

Transurethral prostate resection has been introduced as the surgical treatment of choice in patients with benign prostatic hyperplasia. However, open prostatectomy still has a place. Suprapubic prostatectomy with no bladder drainage and no bladder neck suture appeared to be successful in decreasing convalescence and hospitalization times, with no significant complication, major blood loss, or bladder neck contracture.

A huge left Staghorn kidney, a case report of inevitable open surgery: a case report

INTRODUCTION

Urolithiasis is a very common problem, especially in industrialized societies. Extracorporeal shockwave lithotripsy, percutaneous nephrolithotomy, and transureteral lithotripsy are effective less invasive treatments of renal and ureteral stones. Open stone surgery is used less commonly due to its invasiveness and availability of above mentioned techniques. We introduce a case, that due to heavy and complex stone burden and increased chance of failure of percutaneous nephrolithotomy, Open stone surgery is performed for stone removal.

CASE PRESENTATION

The patient is a 55-years-old Iranian patient that referred to urology department due to a large left Staghorn kidney. After full evaluation and due to extensive spread of stone horns to the even peripheral calyces, open stone surgery performed successfully, that postoperative dynamic renal studies revealed, near normal functional left kidney.

CONCLUSION

In spite of wonderful advances in endourologic stone surgery, open stone surgery still has its role, but it must be done in experienced centers with good surgical expertise to retain good and acceptable functional kidney, postoperatively.
