Patient reported outcomes of intermittent self-dilatation after direct vision internal urethrotomy.

PURPOSE: Long-term results on quality of life (QoL) as well as clinical outcomes of intermittent self-dilatation (ISD) of the urethra after direct visual internal urethrotomy (DVIU) are scarce. The aim of this study was to prospectively evaluate patient reported outcomes (PROs) on voiding symptoms and QoL in a large cohort of urethral stricture patients performing ISD. METHODS: We identified a total of 121 patients who performed ISD following DVIU between 2008 and 2013. Baseline assessment was conducted for each patient before ISD was started. Follow-up visits were scheduled in 6-month intervals. Each assessment included the following questionnaires: International prostate symptom score (IPSS), IPSS quality of life index (IPSS-QoL), patient global impression of severity (PGI-S), and patient global impression of improvement (PGI-I). Additional parameters were maximum urinary flow rate (Qmax ), postvoid residual urine, rate of complications, and stricture recurrence. Linear mixed models were used to examine the change over the course of the follow-up visits to the baseline. RESULTS: The median age of the patients was 58 years (interquartile range [IQR]: 43-70). The median follow-up was 17 months (IQR: 7-30). Mean change from baseline IPSS was -6.1, -5.9, -4.2, and -4.8 points at 6, 24, 36, and 48 months. Mean change from baseline IPSS-QoL was -1.3, -1.4, -1.6, and -1.8 points, respectively. Mean PGI-I was 1.7 points at 6, 1.9 points at 24, 1.9 points at 36, and 2.2 points at 48 months after ISD initiation. Mean change of Qmax ranged from 1.7 at 6 to 2.2 mL/s at 48 months. The median complication rate was 3.3% per 6-month ISD interval. Overall, 11 patients developed stricture recurrence (9%). CONCLUSION: ISD after DVIU had no negative impact on patients' QoL (IPSS-QoL, PGI-I, PGI-S). Urodynamic parameters remained stable for up to 48 months with low complications and an acceptable stricture recurrence rate.

Intermittent self-dilatation for urethral stricture disease in males: A systematic review and meta-analysis.

BACKGROUND: Intermittent self-dilatation (ISD) may be recommended to reduce the risk of recurrent urethral stricture. Level one evidence to support the use of this intervention is lacking. OBJECTIVES: Determine the clinical and cost-effectiveness of ISD for the management of urethral stricture disease in males. SEARCH METHODS: The strategy developed for the Cochrane Incontinence Review Group as a whole (last searched May 7, 2014). SELECTION CRITERIA: Randomised trials where one arm was a programme of ISD for urethral stricture. DATA COLLECTION AND ANALYSIS: At least two independent review authors carried out trial assessment, selection, and data abstraction. RESULTS: Data from six trials that were pooled and collectively rated very low quality per the GRADE approach, indicated that recurrent urethral stricture was less likely in men who performed ISD than those who did not (RR 0.70, 95% CI 0.48-1.00). Two trials compared programmes of ISD but the data were not combined and neither were sufficiently robust to draw firm conclusions. Three trials compared devices for performing ISD, results from one of which were too uncertain to determine the effects of a low friction hydrophilic catheter versus a polyvinyl chloride catheter on risk of recurrent urethral stricture (RR 0.32, 95% CI 0.07 to 1.40); another did not find evidence of a difference between 1% triamcinolone gel for lubricating the ISD catheter versus water-based gel on risk of recurrent urethral stricture (RR 0.68, 95% CI 0.35 to 1.32). No trials gave cost-effectiveness or validated PRO data. CONCLUSIONS: ISD may decrease the risk of recurrent urethral stricture. A well-designed RCT is required to determine whether that benefit alone is sufficient to make this intervention worthwhile and in whom. Neurourol.

Is a Course of Intermittent Self-dilatation with Topical Corticosteroids Superior at Stabilising Urethral Stricture Disease in Men and Improving Functional Outcomes over a Course of Intermittent Self-dilatation Alone? A Systematic Review and Meta-analysis.

Context: Intermittent self-dilatation (ISD) is a therapeutic strategy used to stabilise a urethral stricture and postpone or avoid further treatment. Adding corticosteroids to this mode of management might further enhance its outcomes by downregulation of collagen deposition and excessive scar tissue formation. Objective: To explore whether a course of ISD with topical corticosteroids is superior at stabilising urethral stricture disease in men and improving functional outcomes over a course of ISD alone. Evidence acquisition: This systematic review and meta-analysis was undertaken by the European Association of Urology Urethral Strictures Guideline Panel according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines (CRD42021256744). The primary benefit outcome was successful stabilisation of the urethral stricture. Treatment-related complications were the primary harm outcome. Evidence synthesis: In total, 978 records were screened for eligibility, ultimately leading to five included studies, all randomised controlled trials, comprising 250 patients, of whom 124 underwent a course of ISD with corticosteroids and 126 underwent a course of ISD alone, all after direct vision internal urethrotomy (DVIU). Successful stabilisation of the stricture was achieved in 77% and 64% of patients in the group with and without corticosteroids, respectively (p = 0.04). No extra complications related to the addition of corticosteroids to the ISD regimen were reported. The risk of bias of the included studies was generally unclear to high. Conclusions: Based on the currently available data, a course of ISD with topical corticosteroids appears to be safe and superior at stabilising a urethral stricture after DVIU in the short term to a course of ISD alone. However, given the unclear to high risk of bias in the included studies, further high-quality studies are needed to fully underpin this. Patient summary: This study shows that addition of topical corticosteroids to intermittent self-dilatation after direct vision internal urethrotomy can better stabilise the stricture in the short term.

Outcomes of reintervention after failed urethroplasty.

OBJECTIVE: Urethroplasty is a procedure that has a high success rate. However, there exists a small subgroup of patients who require multiple procedures to achieve an acceptable result. This study analyses the outcomes of a series of patients with failed urethroplasty. MATERIALS AND METHODS: This is a retrospective review of 82 failures out of 407 patients who underwent urethroplasty due to urethral stricture during the period 1999-2013. Failure was defined as the need for an additional surgical procedure. Of the failures, 26 patients had penile strictures and 56 had bulbar strictures. Meatal strictures were not included. RESULTS: The redo procedures included one or multiple direct vision internal urethrotomies, dilatations or new urethroplasties, all with a long follow-up time. The patients underwent one to seven redo surgeries (mean 2.4 procedures per patient). In the present series of patients, endourological procedures cured 34% (28/82) of the patients. Ten patients underwent multiple redo urethroplasties until a satisfactory outcome was achieved; the penile strictures were the most difficult to cure. In patients with bulbar strictures, excision with anastomosis and substitution urethroplasty were equally successful. Nevertheless, 18 patients were defined as treatment failures. Of these patients, nine ended up with clean intermittent self-dilatation as a final solution, five had perineal urethrostomy and four are awaiting a new reintervention. Complicated cases need centralized professional care. CONCLUSION: Despite the possibility of needing multiple reinterventions, the majority of patients undergoing urethroplasty have a good chance of successful treatment.
