OBJECTIVES: Urethral manipulation syndrome (UMS) describes ventral penile curvature and urethral stricture disease that develop following repeated episodes of urethral manipulation. We describe a variant of this syndrome, in which the presence of an indwelling catheter following radical pelvic surgery led to a marked penile curvature without clinically apparent urethral stricture disease. METHODS: We identified 4 patients in whom ventral penile curvature developed following radical pelvic surgery. Three patients underwent radical retropubic prostatectomy and the fourth patient underwent radical cystoprostatectomy with creation of a neobladder to the urethra. All were treated with 3 weeks of catheter drainage postoperatively. Each patient reported straight erections prior to surgery. RESULTS: These patients came to prosthesis surgery between 7 months and 3 years after their pelvic procedure. Each patient was noted to have ventral penile curvature when artificial erection was induced. Curvature was secondary to scarring between the anterior corpus spongiosum and the overlying ventral tunica albuginea in the mid- to proximal penile shaft. It was necessary to mobilize the urethra off the corpora and to incise the scarred tunica to obtain a satisfactory result at the time of prosthesis placement. In 3 cases, GoreTex was needed to bridge the corporeal defect. CONCLUSIONS: These cases represent a variant of UMS in which catheter drainage leads to scarring of the ventral tunica albuginea, resulting in ventral penile curvature. In view of the increasing number of radical pelvic procedures being performed, this potential complication must be recognized, as aggressive corporeal reconstruction with urethral mobilization is needed if subsequent prosthesis surgery is undertaken.

There are some advantages to prospective randomized clinical trials (PRCT) to resolve some limited clinical problems. But, when this method is used to determine the best surgical procedure to close the palatal cleft space, there are strong ethical considerations that cannot be overcome. There are two basic problems. The first is having the surgeon perform surgical procedures which he/she does not believe is the treatment of choice or that can be performed as skillfully as others, even after demonstrations. Secondly, this method does not consider the theoretical aspect that many clefts within the same cleft type are different in the relative size of cleft space to size of soft tissue available for closing the cleft space, thereby creating different degrees of scarring. Different outcomes to the same surgery must, therefore, result irrespective of the surgeons' skills or treatment plans. Retrospective research studies, whether they involve one or more institutions, have been and are still very valuable in improving the knowledge base of all areas of cleft palate habilitation.
