Transurethral resection of the prostate achieves favorable outcomes in stroke patients with symptomatic benign prostate hyperplasia

Anterior fibromuscular stroma-preserved endoscopic enucleation of the prostate: a precision anatomical approach

BACKGROUND

Benign prostate obstruction (BOO) is becoming increasingly important in this aging society. Some urge/stress urinary incontinence (UUI/SUI) still occurs after endoscopic enucleation of the prostate (EEP). It remains unclear how post-EEP incontinence can be avoided. Currently, early apical release to ameliorate the traction of the external sphincter is the best technique for incontinence prevention.

OBJECTIVE

To describe our surgical technique of anterior fibromuscular stroma (AFS)-preserved EEP for BOO.

DESIGN, SETTING, AND PARTICIPANTS

The medical records of 60 consecutive patients who underwent AFS-preserved EEP for BOO in our center from September 2019 to December 2019 were retrospectively reviewed.

SURGICAL PROCEDURE

AFS-preserved EEP starts at the 12 o'clock position of the urethra, and the junction between the AFS and transitional zone (T-zone) was identified. The AFS and T-zone were separated first to protect the AFS in the initial operative procedure. Then, following the usual enucleation procedure, AFS-preserved EEP could be achieved.

MEASUREMENTS

Postoperative prostate-specific antigen (PSA), testosterone, urethral stricture, and voiding status, such as incontinence, uroflow, and postvoiding residual urine were assessed.

RESULTS AND LIMITATIONS

The data show that AFS-preserved EEP could achieve similar surgical outcomes as other early apical release approaches.

CONCLUSIONS

The preserved AFS provides a nice landmark at the 12 o'clock position during EEP.

Surgical outcome of male patients with chronic central nervous system disorders and voiding dysfunction due to bladder outlet obstruction

PURPOSE

Voiding dysfunction is common in patients with chronic central nervous system (CNS) diseases and has great impact on quality of life. Patients with chronic CNS disorders might have concomitant detrusor overactivity, detrusor underactivity, and voiding dysfunction. Although bladder outlet surgeries could relieve bladder outlet obstruction (BOO), patients might have persistent or exacerbated storage symptoms. This study investigated surgical outcome of patients with chronic CNS disorders after bladder outlet surgery.

METHODS

A total of 63 male patients with cerebrovascular accident (CVA, n = 44), Parkinson's disease (PD, n = 11), and early-stage dementia (n = 8), had received bladder outlet surgery after videourodynamic proven BOO refractory to medical treatment. The preoperative and postoperative lower urinary tract symptoms (LUTS) and uroflowmetry parameters were assessed. If the storage symptom subscore decreased or increased by 1, the outcome was considered improved or exacerbated after treatment. When patients had improvement in maximum flow rate (Qmax) and voiding efficiency (VE) and decreased voiding symptom subscore, they were considered having improvement of voiding dysfunction.

RESULTS

The mean age was 71.1 ± 9.8 years and mean duration from diagnosis of BOO to surgical intervention was 15.1 ± 25.0 months. Overall, there was significant improvement in voiding LUTS and urinary retention after surgery. The post-void residual volume (PVR), corrected Qmax (cQmax), and VE significantly improved after surgery. In subgroup analysis, although voiding symptoms improved in CVA patients, urgency and exacerbated urgency incontinence persisted after surgery. In PD patients, there was improvement in voiding condition such as PVR, cQmax and VE, but the storage symptoms did not change after surgery. Patients with dementia had no improvement both in storage and voiding symptoms.

CONCLUSIONS

Bladder outlet surgeries are effective to relieve voiding dysfunction in patients with CVA and PD, but have little effect on storage LUTS in patients with chronic brain lesions.

Can transurethral thermotherapy save elderly patients with benign prostatic obstruction and high ASA score?

INTRODUCTION

The Aim of this study was to investigate the efficacy of the new bipolar radiofrequency prostate thermotherapy method for those with high potential surgical risk and also for patients with a chronic catheter.

MATERIAL AND METHODS

103 patients attending our clinic due to BPO and related complaints with high ASA score had outcomes after the procedure recorded prospectively and investigated retrospectively. Qmax, prostate volume, IPSS score, quality of life score, and presence of catheters were recorded before the procedure and analyzed with the outcomes after the procedure.

RESULTS

The ASA scores were calculated as 3.0 ± 1.0 (IQR). Before the procedure, Qmax values (mean (SD)) were 5.11 ± 5.37 ml/s, while in the 6th month after the procedure Qmax values were identified as 10.45 ± 3.8 ml/s (p < 0.001). Of 53 patients (55.2%) with chronic catheters who could not be operated, 30 (61.2%) no longer required urinary catheter.

CONCLUSION

Bipolar RF thermotherapy appears to be an effective method for patients with BPO who cannot be operated. Due to the surgical risks of patients dependent on the catheter in spite of receiving medical treatment, it is a good alternative to remove catheter dependence. It may be one of the methods that should be remembered, especially in this patient group.

Procalcitonin as an early indicator of urosepsis following prostate biopsy

BACKGROUND

To investigate the usefulness of serum procalcitonin (PCT) in the early diagnosis of urinary tract infection (UTI) and urosepsis following transrectal prostate biopsy.

METHODS

In this prospective observational study, 227 patients who underwent transrectal ultrasound-guided prostate biopsy were evaluated. The relationship between urosepsis and age, serum PCT, C-reactive protein, prostate-specific antigen (PSA), prostate volume, PSA density and pathologic results following biopsy was assessed. Serum PCT level was measured in all patients immediately before the biopsy and at the post-biopsy day 2.

RESULTS

Of the 227 patients, 11 (4.8%) developed UTI with positive urine culture without urosepsis and 5 (2.2%) developed urosepsis within 30 days after biopsy. The concentration of PCT was within the normal range before the biopsy. Procalcitonin concentration at post-biopsy day 2 was significantly higher in patients who developed urosepsis (1.91 ± 2.99 ng/ml vs. 0.05 ± 0.08 ng/ml; p = .004) compared with non-UTI patients. Only elevated PCT level at post-biopsy day 2 was a statistically significant independent predictor of post-biopsy urosepsis. The area under the ROC curve for the prediction of urosepsis was 0.976 (95%CI: 0.941-1.000) and a cut-off 0.095 ng/ml in the level of PCT at post-biopsy day 2 yielded a sensitivity of 100% and specificity of 93.8% in detecting urosepsis following biopsy.

CONCLUSIONS

Procalcitonin appears to be a useful early biomarker to predict the urosepsis following prostate biopsy. Patients with elevated PCT value should be closely monitored after the biopsy.

Clinical features and outcomes of COVID-19 patients with benign prostatic hyperplasia in ageing male: A retrospective study of 18 cases

AIM

A worldwide pandemic of coronavirus disease 2019 (COVID-19) which emerged in China in December 2019 affects the world very seriously. We aimed to evaluate the benign prostatic hyperplasia (BPH) patients who were admitted and treated to our hospital due to COVID-19.

METHODS

Between March 18, 2020 and April 5, 2020, 18 patients admitted with COVID-19 who has BPH and are using medication for this were included in the study and analysed retrospectively. Diagnosis was confirmed by COVID-19 nucleic acid test by sampling sputum or nasopharyngeal swab. Standard COVID-19 treatment protocol determined by our Ministry of Health was applied to all patients according to their risk groups. Epidemiological, clinical, radiological features, additional diseases, laboratory tests, complications and outcome data of all patients were recorded.

RESULTS

Mean age of patients was 59.6 (range: 56-73). As the mode of transmission, 10 (55.5%) of patients were infected in hospital, 5 (27.7%) patients had a relative with COVID-19 and three (16.6%) was unknown. During follow-up, 2 (11.1%) patients were transferred to intensive care unit (ICU). One of these patients dramatically progressed and died. Patients who survived and were not transferred to ICU had lesser comorbidities and were relatively young. Mean duration of hospitalisation was 14.2 days (range 12-19).

CONCLUSION

We think that COVID-19 patients with BPH had a low mortality rate and did not have a poor prognosis in this patient group. It is crucial to take comprehensive preventive measures to control COVID-19 transmission via hospital route.

A Retrospective Study on Risk Factors for Urinary Tract Infection in Patients with Intracranial Cerebral Hemorrhage

Objective

This study aimed to explore the risk factors of urinary tract infection (UTI) in patients with intracranial cerebral hemorrhage (ICH).

Design

This is a retrospective study, and a total of 77 patients with ICH consecutively admitted to the First Affiliated Hospital of USTC (Anhui Provincial Hospital, Hefei, China) during the period of August 2015 to August 2017 were included. The patients were divided into an UTI group (24 cases) and a non-UTI group (53 cases); patients with UTI were diagnosed according to clinical manifestations, recent urinary routines, and urine culture results. The following information in these two groups was recorded: age, sex, course of disease, side of paralysis, location and type of cerebral hemorrhage, disturbance of consciousness or not, the Brunnstrom stage of paralysed lower limbs, number of basic diseases, whether there were complications (tracheotomy, retention catheterization, pulmonary infection, pressure sore, deep venous thrombosis, etc.), whether rehabilitation interventions were conducted, blood routine, biochemistry index, DIC complete set, urine routine, and urine culture data. Univariate analysis and multivariate logistic regression analysis were used to examine the risk factors of UTI in patients with ICH.

Results

Univariate analysis showed that age, side of paralysis, disturbance of consciousness, the Brunnstrom stage of lower limbs, tracheotomies, retention catheterization, pulmonary infection, leukocyte count, neutrophil proportion, sodium, uric acid, D-dimer, and fibrinogen may be related to UTI in patients with ICH (P < 0.05). Regression analysis showed that age (OR (95% CI) = 1.207 (1.022–1.424), P < 0.05). Regression analysis showed that age (OR (95% CI) = 1.207 (1.022–1.424), P < 0.05). Regression analysis showed that age (OR (95% CI) = 1.207 (1.022–1.424), P < 0.05). Regression analysis showed that age (OR (95% CI) = 1.207 (1.022–1.424),

Conclusions

Increased age and high D-dimer are independent risk factors for UTI in patients with ICH, while right-sided paralysis is a protective factor for UTI in patients with ICH.

Association between Bladder Outlet Obstruction and Bladder Cancer in Patients with Aging Male

The associations between the treatment outcomes of benign prostatic hyperplasia/benign prostatic obstruction and lifelong health status, including urologic cancer incidence as well as geriatric adverse events (AEs), are unknown. This retrospective cohort study analyzed claims data collected during the period of 1997–2012 from Taiwan’s Longitudinal Health Insurance Database 2000. Patients who received transurethral resection of the prostate (TURP) were prioritized, and the remaining patients who were prescribed alpha-blockers were, subsequently, identified. Patients in the TURP and medication-only groups were further divided into two groups, according to the presence or absence of AEs during the first six-month follow-up. Outcomes of primary interest were all-cause mortality, occurrence of prostate cancer, transurethral resection of the bladder tumor, and radical cystectomy for bladder cancer. Compared with patients in the AE-free TURP group, those in the TURP with AEs had a higher risk of lifelong bladder cancer (subdistribution hazard ratio: 2.3, 95% confidence interval (CI): 1.56–3.39), whereas the risk of prostate cancer was comparable between the two groups (SHR: 1.2, 95% CI: 0.83–1.74). In the medication cohorts, patients undergoing alpha-blocker treatment who had AEs had a higher risk of all-cause mortality (hazard ratio: 1.63, 95% CI: 1.49–1.78) and a higher risk of lifelong bladder cancer (SHR: 2.72, 95% CI: 1.99–3.71) when compared with those without AE. Our study reveals that unfavorable treatment outcomes of benign prostate hyperplasia, whether caused by medication or surgical treatment, are associated with a higher incidence of bladder cancer. Unfavorable outcomes of surgical treatment are associated with higher risk of geriatric AEs, and unfavorable outcomes of medication treatment are associated with a higher risk of all-cause mortality.

Transurethral resection of the prostate provides more favorable clinical outcomes compared with conservative medical treatment in patients with urinary retention caused by benign prostatic obstruction

Background

To evaluate the long-term surgical outcomes of patients with urinary retention (UR) caused by a benign prostatic obstruction (BPO) who underwent transurethral resection of the prostate (TURP), and compare their outcomes with those of patients who received medication without surgical intervention.

Methods

This retrospective cohort study analyzed claims data collected during the period of 1997–2012 from Taiwan’s National Health Insurance Research Database. We examined geriatric adverse events among patients who had received a diagnosis of symptomatic benign prostatic hyperplasia and whom experienced UR, and compared those who received TURP and medication only. Primary outcomes included urinary tract infection (UTI), UR, inguinal hernia, hemorrhoids, stroke, acute myocardial infarction, and bony fracture. We excluded patients who had concomitant prostate cancer, bladder cancer, or a long-term urinary catheter indwelling, as well as those who did not receive α-blocker medication regularly. Those aged <50 or >90 years were also excluded. The enrolled patients were categorized into TURP (n = 1218) and medication only (n = 795) groups. After 1:1 propensity score matching, we recorded and compared patients’ characteristics, postoperative clinical outcomes, and geriatric adverse events.

Results

The TURP cohort had a lower incidence of UTI and UR during the postoperative follow-up period from 2 months to 3 years than did the medication only group (20.7% vs. 28.9% and 12.5% vs. 27.6%, respectively, p < 0.001). The life-long bone fracture incidence was also lower in the TURP cohort (7.9% vs. 9.2%, p = 0.048). The incidence of other outcomes during the postoperative follow-up period did not differ between the two groups.

Conclusions

Compared with conservative treatment, TURP provides more favorable clinical outcomes in patients with UR caused by BPO. Patients who underwent TURP had a lower risk of UTI, repeat UR episodes, and emergent bony fracture. Thus, early surgical intervention should be considered for such patients.
