A 67-year-old white man presented with bloody diarrhea and passed a 22-cm long segment of full-thickness sigmoid colon following a barium enema. He had advanced peripheral and cerebral vascular disease and had undergone pelvic irradiation for a bladder cancer five years previously. He recovered uneventfully from the bowel sloughage. This was apparently due to an intussusception of the sigmoid colon followed by the formation of adhesions between the edges of the adjacent viable bowel.

After cystoprostatectomy for cancer of the bladder 43 men were provided with a detubularized, low pressure ileal reservoir (Kock pouch) connected to the urethra. Reflux was prevented by an intussusception valve. There was no operative mortality and few early complications. At followup the mean postoperative observation time was 13 months, with a range of 5 to 20 months. Late complications included manifestations of local tumor recurrence or distant metastases in 9 patients within 6 months postoperatively, which made adequate functional evaluation impossible. In 18 patients reflux to the upper urinary tract due to eversion or sliding of the antireflux valve occurred at various postoperative intervals. In 16 of these patients incontinence developed as a consequence of the reflux. Surgical correction of the failing antireflux valve restored reflux prevention and continence. Within 3 to 6 months the capacity of the reservoirs had reached an ultimate volume of approximately 600 ml. Pressure waves exceeding 40 cm. water seldom occurred in the mature reservoirs and then only at high filling volumes. The mean urethral resting resistance to flow was 64 cm. water. The configuration and function of the upper urinary tract improved or stabilized postoperatively. Of 34 evaluable patients 30 were continent during the day with a voiding frequency of 3 to 5 times and dry at night with a frequency of 0 to 2.

From 1983 until July 1994, 561 patients in 2 urology departments (Mainz and Wuppertal) underwent a Mainz pouch 1 procedure. The Mainz pouch 1 was used for bladder augmentation in 60 patients, for orthotopic bladder substitution in 61 patients, and for continent cutaneous urinary diversion in 440 patients. In the group of continent cutaneous urinary diversion, the continence mechanism applied was an ileal intussusception nipple in 270 patients, an appendix stoma in 146 patients, a submucosal seromuscular bowel-flap tube in 14 patients, and a submucosal full-thickness bowel-flap tube in 10 patients. Indications for urinary diversion were bladder cancer in 339 patients, anatomical or functional loss of bladder capacity in 179 patients, and other primary or secondary malignancies of the bladder or true pelvis in 43 patients. After a mean follow-up period of 57 months (range, 3-127 months), early and late complications were encountered in 12% and 37% of the patients, respectively. In the bladder-augmentation group, 93% of the patients are completely continent day and night. All but three patients, who empty their reservoir by intermittent self-catheterization (CIC), void spontaneously by abdominal straining. In the orthotopic bladder-substitution group, 95% of the patients are continent during the daytime. To prevent urinary leakage, 13% have to empty their reservoirs regularly at 4-h intervals and 13% have to perform CIC to avoid residual urine. Among the patients treated with continent cutaneous urinary diversion, stoma failure occurred in 11%, stoma stenosis was encountered in 13% and required open revision in 2%, endoscopical incision in 10%, and conservative treatment (dilation) in 1% of cases.

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.

Intussusception of the large bowel is a rare clinical entity. In adults, this pathology is usually associated with a malignant lead point and often requires operative management. Reported is the case of an 83-year-old female who was recently diagnosed with superficial bladder cancer (T1) treated by partial cystectomy. She presented 3 months post-operatively with an isolated mucosal metastasis of the transverse colon causing intussusception and large bowel obstruction. The patient was successfully treated by colonic resection with primary anastomosis. Histology was significant for a pedunculated sarcomatoid bladder carcinoma originating from the colonic mucosa with incomplete invasion of the bowel wall. An isolated mucosal metastasis of this variety has not been reported in the literature to date.
