Effect of Urethroplasty on Anxiety and Depression.

PURPOSE: To our knowledge anxiety and depression in patients with urethral stricture disease and the impact of urethroplasty on mental health has never been explored. We hypothesized that patients with urethral stricture disease would have higher than normal anxiety and depression levels, and urethroplasty would improve mental health. MATERIALS AND METHODS: We retrospectively reviewed the records of patients in a multi-institutional reconstructive urology database who underwent anterior urethroplasty. Preoperative and postoperative evaluation of anxiety and depression, and overall health was recorded using the validated EQ-5D™-3L Questionnaire. Sexual function was evaluated with the IIEF (International Index of Erectile Function) and the Men's Sexual Health Questionnaire. Stricture recurrence was defined as the need for a subsequent procedure. RESULTS: Median followup in the 298 patients who met study inclusion criteria was 4.2 months. Preoperative anxiety and depression was reported by 86 patients (29%). Those with anxiety and depression reported higher rates of marijuana use, a worse preoperative IIEF score (17.5 vs 19.6, p = 0.01) and a lower image of overall health (66 vs 79, p ≤0.001). Improvement or resolution of anxiety and depression was experienced by 56% of patients treated with urethroplasty while de novo postoperative anxiety and depression were reported by 10%. These men reported a decreased flow rate (16 vs 25 ml per second, p = 0.01). Clinical failure in 8 patients (2.7%) had no effect on the development, improvement or resolution of anxiety and depression. CONCLUSIONS: Of patients with preoperative anxiety and depression 56% reported improvement or resolution after urethroplasty. Although new onset anxiety and depression was rare, these patients had a significantly lower postoperative maximum flow rate, possibly representing a group with a perceived suboptimal surgical outcome. A urethral stricture disease specific questionnaire is needed to further elucidate the interplay of urethral stricture disease with anxiety and depression.

Urethroplasty and Quality of Life: Psychometric Validation of a Dutch Version of the Urethral Stricture Surgery Patient Reported Outcome Measures.

PURPOSE: The study aimed to translate the Urethral Stricture Surgery Patient Reported Outcome Measures (USS-PROM) questionnaire in Dutch. To validate this translated questionnaire, the study evaluates its psychometric properties in a different population, a different environment, and a different health care system. Questions about urinary incontinence and sexual functioning were added. MATERIALS AND METHODS: Between December 2014 and January 2017, Dutch-speaking adult men scheduled for urethroplasty at Ghent University Hospital were prospectively enrolled in this study. Patients completed the USS-PROM before surgery, 3-6 months after surgery, and 1 year after surgery. Psychometric criteria included content validity, criterion validity, internal consistency, reproducibility, responsiveness, and floor and ceiling effects. (EC/2014/0438). RESULTS: A total of 100 patients were included, 39 patients completed both the preoperative and the postoperative questionnaire, and 30 patients completed the USS-PROM twice within a short period of time in order to evaluate test-retest reliability. Pearson correlation coefficients showed no statistical significant correlation between lower urinary tract symptoms (LUTS) scores and maximum flow rates. Cronbach's α was 0.81 and 0.89, respectively, for the LUTS score and the summative Male Sexual Health Questionnaire Ejaculatory Dysfunction short form (MSHQ-EjD short form) score. The intraclass correlation coefficients ranged from 0.72 to 0.94. Significant changes were observed in all items except the MSHQ-EjD short form scores. All values exceeded the predefined thresholds. CONCLUSIONS: The Dutch version of the USS-PROM has adequate psychometric properties and is a valid instrument to assess patient-reported outcome measures in men undergoing urethroplasty.

Comprehensive Qualitative Assessment of Urethral Stricture Disease: Toward the Development of a Patient Centered Outcome Measure.

PURPOSE: The primary objective of this study was to report what patients considered to be the most important symptoms, functions and impacts of urethral stricture disease. Patient and physician perspectives were correlated. MATERIALS AND METHODS: Patients were involved at each step of patient reported outcome measure development. We performed 1) qualitative semistructured concept elicitation interviews, 2) cognitive interviews, 3) prioritization interviews and 4) item prioritization by patients in regard to bother. A total of 22 reconstructive urologists ranked the items in regard to making treatment decisions. RESULTS: Patient qualitative interviews were done until no new information was gained (16 interviews) to reach concept saturation. A total of 40 items were generated from interview data. Urinary items predominated over sexually related content (34 vs 6). A review of published patient reported outcome measures revealed 10 legacy items that were not derived from the qualitative interviews. Two iterative rounds of cognitive interviews were performed in a separate cohort of 5 and 4 patients, respectively, to assess patient comprehension. Item prioritization was done in a separate cohort of 20 patients. The final instrument for validation included 31 items, of which 27 were new and 4 were legacy items. For the top 15 ranked items there was 53% agreement between patients and physicians. Patients were most worried about inability to urinate and urinary dribbling. CONCLUSIONS: We found multiple patient generated concepts related to urinary and sexual impact, function and symptoms. Patients and clinicians had a low agreement rate regarding item importance.

Equipoise across the patient population: optimising recruitment to a randomised controlled trial.

BACKGROUND: This paper proposes a novel perspective on the value of qualitative research for improving trial design and optimising recruitment. We report findings from a qualitative study set within the OPEN trial, a surgical randomised controlled trial (RCT) comparing two interventions for recurrent bulbar urethral stricture, a common cause of urinary problems in men. METHODS: Interviews were conducted with men meeting trial eligibility criteria (n = 19) to explore reasons for accepting or declining participation and with operating urologists (n = 15) to explore trial acceptability. RESULTS: Patients expressed various preferences and understood these in the context of relative severity and tolerability of their symptoms. Accounts suggest a common trajectory of worsening symptoms with a particular window within which either treatment arm would be considered acceptable. Interviews with clinician recruiters found that uncertainty varied between general and specialist sites, which reflect clinicians' relative exposure to different proportions of the patient population. CONCLUSION: Recruitment post referral, at specialist sites, was challenging due to patient (and clinician) expectations. Trial design, particularly where there are fixed points for recruitment along the care pathway, can enable or constrain the possibilities for effective accrual depending on how it aligns with the optimum point of patient equipoise. Qualitative recruitment investigations, often focussed on information provision and patient engagement, may also look to better understand the target patient population in order to optimise the point at which patients are approached.

Psychometric validation of a German language version of a PROM for urethral stricture surgery and preliminary testing of supplementary ED and UI constructs.

PURPOSE: To validate a German language version of the patient-reported outcome measurement (PROM) following urethral stricture surgery (USS) in a cohort of men undergoing one-stage buccal mucosa graft urethroplasty (BMGU) for urethral stricture. Furthermore, to explore the responsiveness of erectile function (EF) and urinary incontinence (UI) constructs in the context of this intervention. METHODS: The USS-PROM captures voiding symptoms (ICIQ-MLUTS) and health-related quality of life (HRQoL) (EQ-5D). To evaluate EF and UI, the IIEF-5 and ICIQ-UI SF were included. Between March 2012 and April 2013, all patients undergoing BMGU at our institution were prospectively enrolled in this study. Psychometric assessment included internal consistency, test-retest reliability, criterion validity and responsiveness. RESULTS: Ninety-three men completed the USS-PROM before and 3 months after surgery, with 40 (43 %) also completing the USS-PROM 6 months after surgery to assess reliability. Internal consistency: for the ICIQ-MLUTS, Cronbach's α was 0.83. The test-retest intraclass correlation coefficient was 0.94. There was a negative correlation between change in ICIQ-MLUTS total score and change in Q max (r = -0.40). All values exceeded our predefined thresholds. Significant improvements of voiding symptoms and HRQoL demonstrate responsiveness to change (all p values <0.001). While ICIQ-UI scores did not change (p > 0.05), IIEF-5 scores improved significantly (p = 0.048). CONCLUSIONS: The German language USS-PROM shows similar psychometric properties to the English language version. This instrument can be improved by assessing EF by the use of IIEF-5. Further studies with larger patient cohorts are needed to evaluate the significance of measuring UI in urethroplasty patients.

[IPSS-QOL questionnaire in assessing symptoms and quality of life in patients with anterior urethral stricture].

RELEVANCE: The IPSS-QOL questionnaire is frequently used to assess symptoms and quality of life of men with urethral strictures. However, the psychometric properties of the questionnaire in assessing these patients have not been evaluated. AIM: To test the psychometric properties of the IPSS-QoL questionnaire in assessing patients with anterior urethral strictures. MATERIAL AND METHODS: Thirty five men with anterior urethral strictures self-completed the IPSS-QoL questionnaire. The reliability of the questionnaire was estimated by computing Cronbachs coefficient and the "point-scale" correlation coefficients. Validity was assessed by the "external criteria" - the correlations between the questionnaire scores and objective indicators - maximum urinary flow rate (Qmax) and residual urine volume (Ures), between QoL scores and index values and EQ-5D scores using a VAS rating scale. RESULTS: The content validity of the IPSS-QoL was assessed by experts and patients: the storage symptoms were found insignificant for patients with anterior urethral stricture, while the symptoms of primary importance (post-micturition dribbling) were not covered. Cronbachs coefficient of reliability was 0.65 (0.55-0.69 with one of the questions removed), i.e. it was below the generally accepted threshold of 0.7. The "point-scale" correlation coefficients ranged from 0.146 to 0.585; for 2 of the 7 questions they were lower, than the conventional threshold of 0.2, showing the internal inconsistencies of the questionnaire. The construct validity assessment showed no correlation between the questionnaire scores and objective indicators Qmax (R=0.178, p=0.306), Ures (R=-0.074, p=0.673). Correlations between QoL scores and index values and EQ-5D scores on the VAS were weak and statistically insignificant: R=-0.26, p=0.18 and R=-0.21, p=0.27, respectively. CONCLUSION: IPSS-QoL questionnaire in assessing men with anterior urethral stricture does not have sufficient reliability and validity. Its design does not allow for adequate assessment of all the symptoms, reliability indices are unsatisfactory, the questionnaire scores do not correlate with objective indicators. This questionnaire cannot be recommended for evaluating health status and quality of life of this category of patients.

[Quality of life as an effectiveness criterion of surgical treatment for anterior urethral strictures].

RELEVANCE: Recent trends in the contemporary medicine have shown a growing request for the personalized choice of treatment and evaluation of its results. PROM-USS questionnaire has been designed for patients undergoing surgical correction of anterior urethral strictures to measure the treatment success using patient reported outcomes in numerical terms. AIM: To test the effectiveness of different surgical modalities for anterior urethral strictures using patient reported outcomes. MATERIAL AND METHODS: Ninety men self-completed the PROM-USS questionnaire after surgical treatment of anterior urethral strictures. Mean and median follow-up was 6-132 months and 72 months, respectively. Measures included lower urinary tract symptom score, overall quality of life (QOL) and overall health, and patient satisfaction with treatment. RESULTS: At the median follow-up of 72 months after surgery for anterior urethral stricture, the survey findings showed LUTS total score 7.4+/-1.2 and urination score on VAS scale 2.3+/-1.1. Sixty-five (72%) of the men believed that residual LUTS did not significantly affect their quality of life. Fifteen (17%) and 10 (11%) patients reported a slight and moderate/strong negative impact of urinary symptoms on their quality of life, respectively. The EQ-5D score of overall health state on VAS was 73+/-4.2 out of 100, the EQ-5D score of the overall quality of life was 0.79+/-0.2. Seventy-eight (86.7%) of 90 men were satisfied (32.2% very satisfied and 54.5% satisfied) with the surgery results, and 12 (13.3%) were dissatisfied. Reasons for dissatisfaction were the emergence of new problems (post-micturition dribbling) with an overall improvement of urinary symptoms (5) and the lack of improvement in urinary symptoms (7). Among patients treated with OIU, 79% were satisfied, which was significantly less than in groups of men who underwent anastomotic urethroplasty - 89% (p<0.05) and substitution urethroplasty using a buccal mucosal grafting - 95% (p<0.05). CONCLUSION: The patient-reported outcomes showed that surgery for anterior urethral stricture is highly effective and characterized by a long term patient satisfaction and quality of life.

[Vesicourethral anastomotic strictures and urinary incontinence following radical prostatectomy: relationship and impact on patients quality of life before and after endoscopic correction].

AIM: To assess the incidence and grade of concomitant stress urinary incontinence (SUI) and the quality of life before and after endoscopic correction of vesicourethral anastomotic strictures (VAS) and the impact of the number of endoscopic interventions on these indicators. MATERIALS AND METHODS: This is a retrospective study of medical records and a telephone survey of patients who underwent radical prostatectomy (RP) at our clinic from 2010 to 2015 and subsequently presented with VAS. The survey included data on the severity of SUI and quality of life using QoL questionnaire before and after endoscopic VAS correction; the factors primarily affecting the quality of life (SUI or obstructive symptoms) were identified. RESULTS: During the above period, 1453 RP were performed. There were 60 VAS cases, of which 56 (93%) were included in the study. Stress urinary incontinence after RP occurred in 64.3% of patients, the average QoL score was 3.95 ( = 0.64; Cv = 16.2%). Before endoscopic VAS correction, 87.5% of patients reported obstructive symptoms as the main cause of dissatisfaction. After endoscopic VAS correction, SUI was observed in 82.1% of patients. De novo incontinence occurred in 15 patients, higher SUI grade was observed in 29 (51.8%) patients. The observed change in the of SUI grade was not statistically significant (paired Students t-test 1.98, p> 0.05). Mean QoL score after endoscopic correction was 2.54 ( = 0.73; Cv = 28.6%, paired Students t-test 5.08, p <0.05). After endoscopic correction of VAS, 78.6% of the patients reported that SUI was the most important factor for decreased quality of life. CONCLUSIONS: The study revealed a high incidence of VAS combined with SIU. There was a significant improvement in patients quality of life after endoscopic correction of VAS, which resulted from a change in the pattern of voiding dysfunction producing a major negative impact on the quality of life. There were no statistically significant correlations between the number of endoscopic corrections of VAS and the SUI grade and the patients quality of life.

Urethral stricture secondary to self-instrumentation due to delusional parasitosis: a case report.

INTRODUCTION: Delusional parasitosis is a rare psychiatric disorder which often presents with dermatological problems. Delusional parasitosis, which involves urethral self-instrumentation and foreign body insertion, is exceptionally rare. This is the first case report to date that provides a detailed presentation of the urological manifestation of delusional parasitosis with complications associated with repeated self-instrumentation and foreign body insertion, resulting in stricture formation and requiring perineal urethrostomy. CASE PRESENTATION: A 45-year-old Irish man was electively admitted for perineal urethrostomy with chronic symptoms of dysuria, haematuria, urethral discharge, and intermittent urinary retention. He reported a 4-year history of intermittent pain, pin-prick biting sensations, and burrowing sensations, and held the belief that his urethra was infested with ticks. He also reported a 2-year history of daily self-instrumentation, mainly injecting an antiseptic using a syringe in an attempt to eliminate the ticks. He was found to have urethral strictures secondary to repeated self-instrumentation. A foreign body was found in his urethra and was removed via cystoscopy. On psychiatric assessment, he displayed a fixed delusion of tick infestation and threatened to surgically remove the tick himself if no intervention was performed. The surgery was postponed due his mental state and he was started on risperidone; he was later transferred to an acute in-patient psychiatric unit. Following a 3-week admission, he reported improvement in his thoughts and distress. CONCLUSIONS: Delusional parasitosis is a rare psychiatric disorder. Self-inflicted urethral foreign bodies in males are rare and have high comorbidity with psychiatric disorders; hence, these patients have a low threshold for referral for psychiatric assessment. The mainstay treatment for delusional parasitosis is second-generation antipsychotic drugs.

Quality and length of life, money and urethral stricture disease.

PURPOSE OF REVIEW: This article walks through some of the ideas behind patient-reported outcome measurement and quality of life research against the backdrop of urethral stricture disease and conditions of the lower urinary tract more generally, why measurement matters at all, future areas for research and development and potential opportunities for misuse and manipulation. RECENT FINDINGS: It is the authors' opinion that only one published study has substantially advanced our understanding of the way men with urethral stricture disease manage this condition in the real world, and, in turn, the outcomes those men seek when they consent to surgery and its associated risks. There is, however, almost certainly greater acceptance now by reconstructive urologists of the utility of patient-reported outcome measures in audit; surgical performance evaluation; clinical research; and fair, logical and transparent healthcare resource allocation at a population level. This is evidenced by the recent proliferation of studies incorporating patient-reported outcomes, which appear today to be on parity at least with those that surgeons historically gave priority to. SUMMARY: The next frontier in urethral stricture disease outcomes research is a better understanding of the impact of this condition on men's daily lives. That level of insight is likely to be gained through a mixture of qualitative and quantitative research methods applied to collaborative research ventures with men with the condition who, as those that have the most to gain and lose, must be majority stakeholders in this process.

How Men Manage Bulbar Urethral Stricture by Concealing Urinary Symptoms.

In this article, we present findings from research conducted as part of a multi-center surgical trial. Bulbar urethral stricture, a narrowing of the middle urethra, is a common cause of urinary problems in men that can have a profound impact on their lives. Semi-structured interviews were conducted with a sample of 19 men seeking treatment for urethral stricture. The findings reveal how men tend to develop routines and tactics to adapt to their symptoms and hide them from others rather than seek help. We argue that this concealment becomes an inseparable part of how the disease is managed and is an additional hidden practical and emotional burden for these men. In addition, we suggest that the patients only sought curative treatments once practices of social concealment are no longer viable.

Poor quality of life in patients with urethral stricture treated with intermittent self-dilation.

PURPOSE: We assessed patient perceptions of regular intermittent self-dilation in men with urethral stricture. MATERIALS AND METHODS: We constructed and distributed a visual analog questionnaire to evaluate intermittent self-dilation via catheterization by men referred for urethral stricture management at a total of 4 institutions. Items assessed included patient duration, frequency, difficulty and pain associated with intermittent self-dilation as well as interference of intermittent self-dilation with daily activity. The primary outcome was patient perceived quality of life. Multivariate analysis was performed to assess factors that affected this outcome. RESULTS: Included in the study were 85 patients with a median age of 68 years, a median of 3.0 years on intermittent self-dilation and a median frequency of 1 dilation per day. On a 1 to 10 scale the median intermittent self-dilation difficulty was 5.0 ± 2.7, the median pain score was 3.0 ± 2.7 and median interference with daily life was 2.0 ± 1.3. Overall quality of life in patients with stricture was poor (median score 7.0 ± 2.6 with poor quality of life defined as 7 or greater). On univariate analysis younger age (p <0.01), interference (p = 0.03), pain (p <0.01) and difficulty performing intermittent self-dilation (p = 0.03) correlated with poor quality of life in a statistically significant manner. On multivariate analysis only difficulty catheterizing (p <0.01) and younger age (p = 0.05) were statistically significant predictors. Patients with stricture involving the posterior urethra had a statistically significant increase in difficulty and decrease in quality of life (each p = 0.04). CONCLUSIONS: Most patients with urethral stricture who are on intermittent self-dilation rate difficulty and pain as moderate, and inconvenience as low but report poor quality of life.

Urethral 'cripples': two-staged procedures.

PURPOSE OF REVIEW: To review the current literature on staged procedures in patients with previous urethral interventions ('urethral cripples'). RECENT FINDINGS: Five studies published during the past 18 months could be identified, the majority with short-term follow-up and small patient numbers. Four studies investigated the outcome after redo surgery in hypospadias patients, one study after urethral stricture disease. SUMMARY: The few data published suggest acceptable complication rate and success rate for surgical outcome. Long-term and prospective data with special respect to sexual function, patient satisfaction, and quality of life are still lacking.

Long-term effect of urethral dilatation and internal urethrotomy for urethral strictures.

PURPOSE OF REVIEW: Urethral dilatation and direct visual internal urethrotomy (DVIU) are widely used minimally invasive options to manage men with urethral strictures. Advances in open urethroplasty with better long-term cure rates have fuelled the continuing debate as to which treatment is best for primary and recurrent urethral strictures. We reviewed recent literature to identify contemporary practice of urethral dilatation and DVIU and the long-term outcome of these procedures. RECENT FINDINGS: Systematic literature search for the period January 2010 to December 2011 showed that urethral dilatation and DVIU remain frequently used treatment options as confirmed by surveys of urologists in the USA and the Netherlands. Multiple reports of laser DVIU confirm the safety of this approach but long-term data were lacking. Stricture free rates from urethra dilatation and DVIU vary from 10 to 90% at 12 months, although adjunctive intermittent self-dilatation can reduce time to recurrence. Although quality-of-life benefit appears good in the short term, repeated procedures may harm sexual function in the long-term. SUMMARY: Urethral dilatation and DVIU remain widely used in urethral stricture management but high-level comparative evidence of benefit and harms against urethroplasty in the short and long-term is still lacking.

Risk factors and quality of life for post-prostatectomy vesicourethral anastomotic stenoses.

OBJECTIVE: To evaluate the difference in vesicourethral anastomotic stenosis (VUAS) rates after open radical retropubic prostatectomy (RRP) vs robot-assisted radical prostatectomy (RARP), and to analyze associated factors and effect on quality of life. METHODS: From 2001 to 2009, a total of 1038 patients underwent RARP and 707 patients underwent open RRP. Perioperative factors and Expanded Prostate Cancer Index Composite (EPIC) quality of life scores were compared between patients who did and did not develop a VUAS. Independent significant predictors of VUAS development were identified using multivariable modeling. RESULTS: The incidence of VUAS in open RRP cases was higher (53/707, 7.5%) than for RARP (22/1038, 2.1%) (P<.0001). Intervention consisted of dilation in 34 of 75 cases (45.3%), internal urethrotomy in 8 of 75 (10.7%), and multiple procedures in 30 of 75 (40%). Open technique (P<.0001, odds ratio [OR]=3.0, 95% confidence interval [CI]=1.8-5.2), prostate-specific antigen (PSA) recurrence (P=.02, OR=2.2, 95% CI=1.2-4.1), postoperative hematuria (P=.02, OR=3.7, 95% CI=1.2-11.3), urinary leak (P=.002, OR=6.0, 95% CI=1.9-19.2), and urinary retention (P=.004, OR=3.5, 95% CI=1.5-8.7) were significant independent predictors of VUAS development. EPIC incontinence scores were similar between VUAS and non-VUAS patients, whereas irritative voiding scores were worse initially with VUAS but became similar by 12 months. CONCLUSION: There is a higher rate of VUAS after open RRP vs RARP. Most cases of VUAS require endoscopic intervention. Predictors include open surgery, PSA recurrence, and postoperative hematuria, urinary leak, and retention. There is no diminution of quality of life scores at 12 months.

[Reconstructive surgery for male urethral stricture affects erectile function and sexual life quality].

OBJECTIVE: To evaluate the influence of reconstructive surgery for male urethral stricture on erectile function and sexual life quality. METHODS: We analyzed retrospectively the clinical data of 326 male patients who underwent urethroplasty for urethral stricture in our department and evaluated their erectile function and sexual life quality. RESULTS: A total of 172 groups of valid data were collected, with the mean follow-up of 28.5 months. The mean scores on IIEF-5 (P=0.002) and sexual life quality (P=0.026) were statistically significantly reduced after surgery. Erectile dysfunction was found in 88 (51.2%) of the patients after urethroplasty, as compared with 56 (32.6%) preoperatively. CONCLUSION: The location of urethral stricture, surgical method and urethral stricture recurrence may affect the erectile function and sexual life quality of the patient, but both can be gradually improved with the time after urethroplasty.

Low-power holmium:YAG laser urethrotomy for treatment of urethral strictures: functional outcome and quality of life.

PURPOSE: To evaluate the efficacy of endourethrotomy with the holmium:YAG laser as a minimally invasive treatment for urethral stricture. PATIENTS AND METHODS: Between January 2002 and January 2004, 32 male patients with symptomatic urethral strictures (8 bulbar, 9 penile, 9 combined) were treated with Ho:YAG-laser urethrotomy in our department. The stricture was iatrogenic in 60% (N = 18), inflammatory in 16.6% (N = 5), traumatic in 13.3% (N = 4), and idiopathic in 7% (N = 3). The stricture was incised under vision at the 12 o'clock location or the site of maximum scar tissue or narrowing in asymmetric strictures. Laser energy was set on 1200 to 1400 mJ with a frequency of 10 to 13 Hz. Postoperatively, drainage of the bladder was performed for 4 days using a 18F silicone catheter. Triamcinolone was instilled intraurethrally after removal of the catheter in all patients. Patients were followed up by mailed questionnaire, including International Prostate Symptom Score and quality of life. RESULTS: Retrograde endoscopic Ho:YAG laser urethrotomy could be performed in all 32 patients. Most patients (22; 68.7%) did not need any reintervention. Ten patients developed recurrent strictures that were treated by another laser urethrotomy in 4 patients (12.5%), while 6 patients (18.7%) needed open urethroplasty with buccal mucosa. Including 2 patients treated with repeat laser urethrotomy, 24 patients (75%) were considered successful after a mean follow-up of 27 months (range 13-38 months). No intraoperative complications were encountered, although in 5% of patients, a urinary-tract infection was diagnosed postoperatively. No gross hematuria occurred. CONCLUSIONS: The Ho:YAG laser urethrotomy is a safe and effective minimally invasive therapeutic modality for urethral stricture with results comparable to those of conventional urethrotomy. Further data from long-time follow-up are necessary to compare the success rate with that of conventional urethrotomy and urethroplasty. Nevertheless, the Ho:YAG laser urethrotomy might at least be an alternative to urethroplasty in patients with high comorbidity who are not suitable for open reconstruction.

Urethral stricture at Ahmadu Bello University Teaching Hospital, Zaria.

We reviewed 556 male urethral strictures treated at Ahmadu Bello University Teaching Hospital, Zaria between 1980 and 1989. Their ages ranged from nine to 80 years with a mean of 40 +/- 12.9 SD years. Infection caused stricture in 66.5% while trauma accounted for 31.7%. Urethral injury associated with pelvic fracture from road traffic accident accounted for 68% of the traumatic causes. Inflammatory strictures were mainly located in the bulbar urethra (69.9%), while most traumatic ones involved membranous urethra (74.4%). Inflammatory strictures were mostly multiple (85%) while 90% of traumatic ones were single. Many patients with inflammatory strictures had more than one episode of urethritis. About 58% of the patients were treated by dilatation, 16% by visual internal urethrotomy and 26% by urethroplasty. Best results were obtained in patients treated by urethroplasty where 72% were satisfied with their treatment. Overall, 61% of the patients were satisfied with their treatment and were voiding urine without effort at two years. Re-stricture occurred in 21% and 23% of patients treated by urethroplasty and internal urethrotomy respectively. Urethroplasty is advocated upon less strict indications where the expertise is available.
