          Abstract

          Male anterior urethral stricture disease is a commonly encountered condition that presents to many urologists. According to a National Practice Survey of Board Certified Urologist in the United States most urologists treat on average 6-20 urethral strictures yearly. Many of those same urologists surveyed treat with repeated dilation or internal urethrotomy, despite continual recurrence of the urethral stricture. In point of fact, the urethroplasty despite its high success rate, is underutilized by many practicing urologists. Roughly half of practicing urologist do not perform urethroplasty in the United States. Clearly, the reconstructive ladder for urethral stricture management that was previously described in the literature may no longer apply in the modern era. The following article reviews the etiology, diagnosis, management and comparisons of treatment options for anterior urethral strictures.

          Etiology of urethral stricture disease in the 21st century.

          We determined the current etiology of urethral stricture disease in the developed world and whether there are any differences in etiology by patient age and stricture site. Between January 2001 and August 2007 we prospectively collected a database on 268 male patients with urethral stricture disease who underwent urethroplasty at a referral center. The database was analyzed for possible cause of stricture and for previous interventions. Subanalysis was done for stricture etiology by patient age and stricture site. The most important causes were idiopathy, transurethral resection, urethral catheterization, pelvic fracture and hypospadias surgery. Overall iatrogenic causes (transurethral resection, urethral catheterization, cystoscopy, prostatectomy, brachytherapy and hypospadias surgery) were the etiology in 45.5% of stricture cases. In patients younger than 45 years the main causes were idiopathy, hypospadias surgery and pelvic fracture. In patients older than 45 years the main causes were transurethral resection and idiopathy. In cases of penile urethra hypospadias surgery idiopathic stricture, urethral catheterization and lichen sclerosus were the main causes, while in the bulbar urethra idiopathic strictures were most prevalent, followed by strictures due to transurethral resection. The main cause of multifocal/panurethral anterior stricture disease was urethral catheterization, while pelvic fracture was the main cause of posterior urethral strictures. Of strictures treated with urethroplasty today iatrogenic causes account for about half of the urethral stricture cases in the developed world. In about 1 of 3 cases no obvious cause could be identified. The etiology is significantly different in younger vs older patients and among stricture sites.

            Treatment of male urethral strictures: is repeated dilation or internal urethrotomy useful?

            We evaluate the efficacy of repeated dilation or urethrotomy as treatment of male urethral strictures. Between January 1991 and January 1994, 210 men with proved urethral strictures were prospectively randomized to undergo filiform dilation (106) or internal urethrotomy (104). Followup was scheduled at 3, 6, 9, 12, 24, 36 and 48 months. Dilation or internal urethrotomy was repeated at the first and second stricture recurrence. The Kaplan-Meier method was used to estimate survivor function for the treatment methods (survival time being the time to first stricture recurrence) and the log rank test was used to compare the efficacy of different treatments. Followup (mean 24 months, range 2 to 63) was available in 163 patients (78%). After a single dilation or urethrotomy not followed by re-stricturing at 3 months, the estimated stricture-free rate was 55 to 60% at 24 months and 50 to 60% at 48 months. After a second dilation or urethrotomy for stricture recurrence at 3 months the stricture-free rate was 30 to 50% at 24 months and 0 to 40% at 48 months. After a third dilation or urethrotomy for stricture recurrence at 3 and 6 months the stricture-free rate at 24 months was 0 (p <0.0001). Dilation and internal urethrotomy are useful in a select group (approximately 70% of all patients) who are stricture-free at 3 months, and of whom 50 to 60% will remain stricture-free up to 48 months. A second dilation or urethrotomy for early stricture recurrence (at 3 months) is of limited value in the short term (24 months) but of no value in the long term (48 months), whereas a third repeated dilation or urethrotomy is of no value.

              Long-term results of open transvesical prostatectomy from a contemporary series of patients.

              To provide information about the long-term efficacy of transvesical prostatectomy from a contemporary series of patients. When comparing minimally invasive procedures with open prostatectomy, the data for the latter are usually provided from old studies or from recent ones performed in developing countries. However, this procedure is still used frequently for large-size prostates. During a 5-year period, 232 patients with large (greater than 75 g) prostates underwent open transvesical prostatectomy for symptomatic benign prostatic hyperplasia. Patient charts were retrospectively reviewed for preoperative and postoperative International Prostate Symptom Scores, postvoid residual urine volumes, maximal flow rates, early and late postoperative complications, and the need for reoperation. The preoperative International Prostate Symptom Score, postvoid residual urine volume, and maximal flow rate were compared with the corresponding postoperative data at 8 to 12 months and at the last follow-up visit. Complete data evaluation was possible for 151 patients, with a mean follow-up of 41.8 +/- 15.6 months. Improvement in International Prostate Symptom Score, postvoid residual urine volume, and maximal flow rate was statistically significant (P <0.001) at 8 to 12 months and remained statistically significant at the last follow-up visit. Long-term complications included bladder neck contraction in 5 (3.3%) occurring at a mean of 10 months (range 5 to 17), urethral strictures in 1 (0.6%), and meatal stenosis in 2 (1.3%) of 151 patients. Re-operation was required in 6 patients (3.9%). Transvesical prostatectomy in a contemporary series of patients proved to be successful, with a low rate of complications. Its success has a durable effect and only rarely was a corrective procedure necessary. This approach should be included in the list of possible treatments to discuss with the patient with a large prostate.
