Lower urinary tract symptoms (LUTS) in aging men are commonly attributed to bladder outlet obstruction from benign prostatic hyperplasia (BPH) but BPH/LUTS often reflects a confluence of many factors. We performed a hierarchical cluster analysis using four objective patient characteristics (age, HTN, DM, and BMI), and five pre-operative urodynamic variables (volume at first uninhibited detrusor contraction, number of uninhibited contractions, Bladder Outlet Obstruction Index (BOOI), Bladder Contractility Index (BCI) and Bladder Power at Qmax) to identify meaningful subgroups within a cohort of 94 men undergoing surgery for BPH/LUTS. Two meaningful subgroups (clusters) were identified. Significant differences between the two clusters included Prostate Volume (95 vs 53 cc; p-value = 0.001), BOOI (mean 70 vs 49; p-value = 0.001), BCI (mean 129 vs 83; p-value <0.001), Power (689 vs 236; p-value <0.001), Qmax (8.3 vs 4.9 cc/sec; p-value <0.001) and post-void residual (106 vs 250 cc; p-value = 0.001). One cluster is distinguished by larger prostate volume, greater outlet resistance and better bladder contractility. The other is distinguished by smaller prostate volume, lower outlet resistance and worse bladder contractility. Remarkably, the second cluster exhibited greater impairment of urine flow and bladder emptying. Surgery improved flow and emptying for patients in both clusters. These findings reveal important roles for both outlet obstruction and diminished detrusor function in development of diminished urine flow and impaired bladder emptying in patients with BPH/LUTS.

Fetal lower urinary tract obstruction (LUTO) is associated with high perinatal and long-term childhood mortality and morbidity. We aimed to assess the effectiveness of vesicoamniotic shunting for treatment of LUTO. In a randomised trial in the UK, Ireland, and the Netherlands, women whose pregnancies with a male fetus were complicated by isolated LUTO were randomly assigned by a central telephone and web-based randomisation service to receive either the intervention (placement of vesicoamniotic shunt) or conservative management. Allocation could not be masked from clinicians or participants because of the invasive nature of the intervention. Diagnosis was by prenatal ultrasound. The primary outcome was survival of the baby to 28 days postnatally. All primary analyses were done on an intention-to-treat basis, but these results were compared with those of an as-treated analysis to investigate the effect of a fairly large proportion of crossovers. We used Bayesian methods to estimate the posterior probability distribution of the effectiveness of vesicoamniotic shunting at 28 days. The study is registered with the ISRCTN Register, number ISRCTN53328556. 31 women with singleton pregnancies complicated by LUTO were included in the trial and main analysis, with 16 allocated to the vesicoamniotic shunt group and 15 to the conservative management group. The study closed early because of poor recruitment. There were 12 livebirths in each group. In the vesicoamniotic shunt group one intrauterine death occurred and three pregnancies were terminated. In the conservative management group one intrauterine death occurred and two pregnancies were terminated. Of the 16 pregnancies randomly assigned to vesicoamniotic shunting, eight neonates survived to 28 days, compared with four from the 15 pregnancies assigned to conservative management (intention-to-treat relative risk [RR] 1·88, 95% CI 0·71–4·96; p=0·27). Analysis based on treatment received showed a larger effect (3·20, 1·06–9·62; p=0·03). All 12 deaths were caused by pulmonary hypoplasia in the early neonatal period. Sensitivity analysis in which non-treatment-related terminations of pregnancy were excluded made some slight changes to point estimates only. Bayesian analysis in which the trial data were combined with elicited priors from experts suggested an 86% probability that vesicoamniotic shunting increased survival at 28 days and a 25% probability that it had a large, clinically important effect (defined as a relative increase of 55% or more in the proportion of neonates who survived). There was substantial short-term and long-term morbidity in both groups, including poor renal function—only two babies (both in the shunt group) survived to 2 years with normal renal function. Seven complications occurred in six fetuses from the shunt group, including spontaneous ruptured membranes, shunt blockage, and dislodgement. These complications resulted in four pregnancy losses. Survival seemed to be higher in the fetuses receiving vesicoamniotic shunting, but the size and direction of the effect remained uncertain, such that benefit could not be conclusively proven. Our results suggest that the chance of newborn babies surviving with normal renal function is very low irrespective of whether or not vesicoamniotic shunting is done.

Introduction and hypothesis Common options for management of primary bladder neck obstruction (PBNO) in women include medications and surgical treatment. Less invasive treatment such as bladder neck botulinum toxin injection can be an alternate therapy in patients with failed conservative management. In this study, we describe the subjective and objective outcomes, patient satisfaction, and willingness for repeat treatment with bladder neck botulinum toxin injection in females with PBNO. Methods A retrospective analysis of ten female PBNO patients managed with bladder neck botulinum toxin injection was performed. Subjective parameters were quantified with symptom assessment, International Prostate Symptom Score (IPSS), and Quality of life (QoL) score. Objective parameters were assessed with maximum flow rate (Qmax) in uroflowmetry and postvoid residual (PVR). Results The mean pre-treatment IPSS, QoL score, Qmax, PVR was 24.2 ± 5.0, 4.8 ± 0.63, 5.73 ± 3.18 ml/s, and 210 ± 66 ml, respectively. Seven of the ten patients subjectively improved (IPSS 12.9 ± 9.6, QoL2.9 ± 1.6, p  < 0.05). Three patients improved objectively (mean Qmax 17.3 ± 2.7 ml/s, PVR 42.7 ± 7.5 ml, p  < 0.05). Three patients accepted repeat botulinum toxin injection. Three patients who showed no improvement underwent bladder neck incision with resolution of symptoms. Conclusion Botulinum toxin can be an intermediary therapy in female patients with PBNO who want a minimally invasive procedure.

PURPOSE: To compare the outcomes of patients undergoing robotic YV plasty for bladder neck contracture (BNC) vs. vesico-urethral anastomotic stricture (VUAS). METHODS: A retrospective study included male patients who underwent robotic YV plasty for BNC after endoscopic treatment of BPH or VUAS between August 2019 and March 2023 at a single academic center. The primary assessed was the patency rate at 1 month post-YV plasty and during the last follow-up visit. RESULTS: A total of 21 patients were analyzed, comprising 6 in the VUAS group and 15 in the BNC group. Patients with VUAS had significantly longer operative times (277.5 vs. 146.7 min; p = 0.008) and hospital stay (3.2 vs. 1.7 days; p = 0.03). Postoperative complications were more common in the VUAS group (66.7% vs. 26.7%; p = 0.14). All patients resumed spontaneous voiding postoperatively. Five patients (23.8%) who developed de novo stress urinary incontinence had already an AUS (n = 1) or required concomitant AUS implantation (n = 3), all of whom were in the VUAS group (83.3% vs. 0%; p < 0.0001). The proportion of patients improved was similar in both groups (PGII = 1 or 2: 83.3% vs. 80%; p = 0.31). Stricture recurrence occurred in 9.5% of patients in the whole cohort, with no significant difference between the groups (p = 0.50). Long-term reoperation was required in three VUAS patients, showing a statistically significant difference between the groups (p = 0.05). CONCLUSION: Robotic YV plasty is feasible for both VUAS and BNC. While functional outcomes and stricture-free survival may be similar for both conditions, the perioperative outcomes were less favorable for VUAS patients.

Purpose Bladder neck stricture (BNS) is a bothersome disease which may affect patients after trauma or prostatic surgery. It is frustrating due to the low durable success rate of currently available surgical techniques. The aim of the study is to explore the efficacy of a novel technique. Materials & methods The surgical protocol was developed by two high case-volume surgeons. The technique consists of Holmium laser incisions at 3–6-9–12 o’clock. Subsequently, triamcinolone acetonide 40 mg is injected. Two months later, the BNS is endoscopically checked in operatory room and re-procedure take place, if necessary (max 3 times). Failure was defined as the need of definitive urinary diversion. Subjective satisfaction was measured through PGI-I Questionnaire. Results A total of 45 patients were enrolled. Median age was 63 (IQR 59–69) years and BNS developed by different causes. Naïve BNS procedure patients were 12 (26.7%), others 33 (73.3%) underwent median 2 (IQR 1–4) previous urethrotomies, including 16 other surgeries. Suprapubic bladder catheter was present in 34 patients (75.6%). No complications were registered. Re-procedure at control was necessary in 24 patients (53.3%) for a median of 1 (IQR 1–3) procedures. At median follow-up of 18 months, failures were 4 (8.9%) and urinary incontinence was reported in 2 patients (4.5%) who required incontinence surgery. Median PGI-I was 2. Conclusions Our technique of BNS treatment allows good outcomes and high rate of subjective improvement amongst patients. Moreover, naïve patients seem to have better results. However, longer follow-up and higher sample size are mandatory to further assess these data.

Cystitis cystica and glandularis is a rare pathological condition characterised by cystic and glandular proliferations of the bladder wall. This case report presents a unique instance of bladder outlet obstruction (BOO) caused by this condition at the bladder neck, emphasising clinical manifestations, surgical intervention and postoperative outcomes. A literature review further contextualises this diagnosis within urology.

The latest update of the EAU Guidelines on Management of Non - Neurogenic Male Lower Urinary Tract Symptoms, incl. Benign Prostatic Obstruction in 2016 announced a novel acronym for transurethral Endoscopic Enucleation of the Prostate (EEP). This was inspired by a meta-analysis on randomized controlled trials on Holmium Laser Enucleation of the Prostate (HolEP) and bipolar enucleation versus open simple prostatectomy. EEP codes for the common ground of both techniques: “anatomical enucleation.” Although study quality with regard to the availability of long-term randomized controlled trials is at the moment mostly available for HoLEP, and bipolar enucleation, the existing data of all other enucleating techniques that have been demonstrated to perform anatomical enucleation as well should also been summarized under the same term. This editorial is a call for embracing this acronym of EEP for all anatomical enucleating techniques in order to serve for the transition from the age of TURP and open prostatectomy toward the age of EEP.

Background Lower urinary tract symptoms (LUTS) comprise storage symptoms, voiding symptoms and post-voiding symptoms. Prevalence and severity of LUTS increase with age and the progressive increase in the aged population group has emphasised the importance to our society of appropriate and effective management of male LUTS. Identification of causal mechanisms is needed to optimise treatment and uroflowmetry is the simplest non-invasive test of voiding function. Invasive urodynamics can evaluate storage function and voiding function; however, there is currently insufficient evidence to support urodynamics becoming part of routine practice in the clinical evaluation of male LUTS. Design A 2-arm trial, set in urology departments of at least 26 National Health Service (NHS) hospitals in the United Kingdom (UK), randomising men with bothersome LUTS for whom surgeons would consider offering surgery, between a care pathway based on urodynamic tests with invasive multichannel cystometry and a care pathway based on non-invasive routine tests. The aim of the trial is to determine whether a care pathway not including invasive urodynamics is no worse for men in terms of symptom outcome than one in which it is included, at 18 months after randomisation. This primary clinical outcome will be measured with the International Prostate Symptom Score (IPSS). We will also establish whether inclusion of invasive urodynamics reduces rates of bladder outlet surgery as a main secondary outcome. Discussion The general population has an increased life-expectancy and, as men get older, their prostates enlarge and potentially cause benign prostatic obstruction (BPO) which often requires surgery. Furthermore, voiding symptoms become increasingly prevalent, some of which may not be due to BPO. Therefore, as the population ages, more operations will be considered to relieve BPO, some of which may not actually be appropriate. Hence, there is sustained interest in the diagnostic pathway and this trial could improve the chances of an accurate diagnosis and reduce overall numbers of surgical interventions for BPO in the NHS. The morbidity, and therapy costs, of testing must be weighed against the cost saving of surgery reduction.

Purpose The purpose of this study was to assess the bladder and renal functional outcomes of holmium laser enucleation of the prostate (HoLEP) in patients with benign prostatic obstruction (BPO) complicated by detrusor underactivity (DU) and secondary renal dysfunction. Methods Thirty-one patients were included in this prospective study. Eligible patients had urinary retention, a bladder outlet obstruction index (BOOI) greater than 40, a bladder contractility index (BCI) less than 100, abnormal renal function at the initial diagnosis (serum creatinine > 132 µmol/L) and a renal pelvis anteroposterior diameter (PRAPD) > 1.5 cm bilaterally. All patients underwent HoLEP in a routine manner and were evaluated preoperatively and at 1, 3 and 6 months after surgery. The baseline characteristics of the patients, perioperative data, postoperative outcomes and complications were assessed. Results Significant improvement was observed in the international prostate symptom score (IPSS), quality of life (QoL) score, maximal urinary flow rate (Qmax), post-void residual volume (PVR), Scr and RPAPD at the 6-month follow-up. Bladder wall thickness (BWT) exhibited a decreasing trend but did not significantly differ from the preoperative values. No grade 3 or higher adverse events occurred, and grade 3 and lower complications were treated conservatively. Three patients required reinsertion of indwelling catheters, and they were able to void spontaneously after two weeks of catheterisation training and medication treatment. Conclusion HoLEP is an effective treatment for men with BPO accompanied by DU and consequent renal function impairment. Patients are able to regain spontaneous voiding. Both bladder and renal functions were preserved and improved.

Purpose To determine success rate (SR), functional outcome, and patient satisfaction of a modified YV-plasty for reconstruction of the bladder neck in case of recurrent bladder neck stenosis (BNS) after transurethral surgery of the prostate: the T-plasty. Patients and methods We identified all patients who underwent T-plasty at our center between December 2008 and July 2016. Patients’ charts were reviewed. Patients were queried by telephone and by mail at time of follow-up (FU). Primary endpoint was SR. Secondary endpoints were complications, continence, satisfaction, and changes in quality of life measured by validated questionnaires. Results Thirty patients underwent the T-plasty. Median age at surgery was 69 (IQR 62–73) years. Most patients had BNS due to TUR-P [ n  = 25 (83.3%)]. No severe blood loss or severe complications occurred perioperatively. Median FU was 45 (IQR 18–64) months. Three patients were lost to FU. Success rate was 100%. Compared to pre-OP Q max , mean Q max post-OP improved significantly [pre-OP 6.79 (SD ± 4.76) ml/s vs post-OP was 24.42 (SD ± 12.61) ml/s; ( t (5) = 4.12, p  = 0.009)]. Mean post-void residual urine decreased significantly [pre-OP 140.77 (SD ± 105.41) ml vs post-OP 14.5 (SD ± 22.42) ml; ( t (9) = −3.86, p  = 0.004)]. One patient developed a de-novo-incontinence post-OP. Mean ICIQ-SF Score was 1.2 (SD ± 2.27). 88.5% of patients were pleased or delighted by surgery. 75% of patients claimed their quality of life has been (strongly) improved. Conclusions The T-plasty is a valuable option as treatment of recurrent BNS. SR, rates of continence, and high patient satisfaction are very encouraging.
