Prostate cancer, bladder cancer, and pelvic floor weakness are among the most common diseases of the pelvis. Cardinal symptoms include painless macrohematuria in bladder cancer and urinary and fecal incontinence in pelvic floor weakness. Suspicion of prostate cancer currently is most frequently raised when the serum concentration of prostate-specific antigen is pathologically elevated. Besides extensive clinical and invasive diagnosis, clinical imaging is frequently applied for the localization, locoregional staging, and diagnosis of recurrence of prostate cancer and invasive bladder cancer, and in clinically difficult cases of cystocele, enterocele, rectocele, descensus or prolapse of vagina, uterus, and rectum, and rectal intussusception. Magnetic resonance imaging with T2-weighted TSE or FSE images in several planes combined with either axial, T1-weighted images and MR spectroscopy for the prostate, dynamic contrast-enhanced T1-weighted images for the urinary bladder, or dynamic T2-weighted functional images for pelvic floor incontinence are particularly well suited as clinical imaging methods.

The advent of prostate-specific antigen screening has changed the global epidemiology of prostate cancer, with men being diagnosed with organ-confined cancer at a younger age. Radical prostatectomy with curative intent for these patients, while delivering excellent long-term survival outcomes, still has significant side effects, chiefly postprostatectomy incontinence. Increasing age, shorter pre- and post-operative membranous urethral length, anastomotic strictures, obesity, low surgeon volume, variations of surgical technique and previous prostate surgery have been reported as negative risk factors for delayed continence recovery and/or permanent incontinence following radical prostatectomy. Significant progress in elucidating the functional anatomy and physiology of the male continence mechanism from cadaveric and videourodynamic studies have enabled surgeons to propose innovative surgical techniques during radical prostatectomy for augmenting continence preservation and early return. These have included optimizing the preservation of urethral rhabdosphincter length; avoiding rhabdosphincter injury; posterior reconstruction of Denonvilliers' musculofascial plate; preservation of the bladder neck and internal sphincter; bladder neck intussusception; bladder neck mucosal eversion; preservation of the puboprostatic ligaments and arcus tendineus; and preservation of putative nerves supplying the continence mechanism. We review the scientific and technical advances in continence recovery following radical prostatectomy, identify the key principles undergirding early return of continence, highlight various treatment strategies for early and refractory postprostatectomy incontinence and describe our experience with a paradigm of these unified key principles. Increasing application of these principles in computer-aided (robotic), minimally invasive and minimal-access (i.e., single-port or natural orifice transluminal) approaches will hopefully enable patients to derive maximal benefit from curative prostatectomy while experiencing early return of continence in the not too distant future.

Meckel diverticulum is a common congenital malformation of the gastrointestinal tract and can cause complications such as ulceration, hemorrhage, intussusception, and perforation. This report describes a very rare complication of an enterovesical fistula associated with chronic Meckel diverticulum. A 51-year-old male presented with over 10 years of persistent pyuria. Tests were performed to rule out malignancy, including serum prostate-specific antigen level, urine cytology, bacterial culture, cystoscopy, and bladder computed tomography. An enterovesical fistula was identified, and laparoscopic exploration was performed. The findings suggested enterovesical fistula formation caused by chronic inflammation at the tip of a Meckel diverticulum. Segmental resection of the small bowel including the diverticulum and primary repair of the urinary bladder along with partial cystectomy were performed. The postoperative clinical course was uneventful. An enterovesical fistula is a very rare complication resulting from chronic inflammation of a Meckel diverticulum.
