Eight patients who received en bloc excision of the ureter and internal iliac vessels for locally advanced upper rectal and rectosigmoid cancer were reported. Indications, techniques, functional results of the ileal ureter, and prognosis of these patients are discussed. Although three patients died of recurrent tumor--one of transperitoneal spread and two of liver metastasis--none of them developed local recurrent growth. As a replacement for the resected ureter, ileal substitution was applied in all eight patients--unilateral in six patients and bilateral in two. Serum creatinine and electrolyte patterns were within the normal range in all patients. A voiding cystogram showed no reflux to the anastomosed ureter, and a mild reflux to the ileal segment. The patients had excellent prognoses with regard to local control and also satisfactory functional results with the ileal ureter. The authors recommend that this procedure be applied to patients with locally advanced cancer such as those in this series.

Neoplasia associated with ureterosigmoidostomy is uncommon but important. Two patients, one of whom developed symptoms five years after the ureterosigmoidostomy had been taken down, are reported. The authors support the theory that these tumors may arise from the ureter. When ureterosigmoidostomies are dismantled, the site of implantation should be resected and the patients kept under long-term endoscopic review.

Two cases are presented where changes at ureteoenteric anastomoses masqueraded as neoplastic polyps that resulted in excision of the tip of the implanted ureter in one patient. The colonoscopist should be aware of this possibility and endeavor to identify the exact location of the ureteric orifices before excision of any polypoid lesion in this situation.

Damage to the ureter is uncommon. In this series, the damage has been either elective, accidental or delayed. In the occasional patient the damage was repaired, but in most a nephrectomy was necessary.

Eighteen cases of penetrating ureteral injury encountered over 10 years are reviewed. Low-velocity gunshot was the mode of injury in 16. All levels of the ureter were represented with near-equal incidence. Stented uretero-ureterostomy was the primary mode of management, offering satisfactory results, with temporary urine leaks resolving spontaneously in four, responding to temporary catheter diversion in one, and requiring reoperation in two. Plastic stenting was inferior to silastic or rubber materials. Colon and/or bowel injury was universal and was not found to justify alteration in choice of surgical timing or technique, or to influence overall results. Adequately drained urine poses no threat to cicatricial stenosis. Urography is reliable; retrograde studies are dependable when urography is equivocal.

We reviewed 18 cases of penetrating ureteral injury encountered during a 10-year interval. Low velocity gunshot injuries occurred in 16 patients. All levels of the ureter were represented with near equal incidence. Stented ureteroureterostomy was the primary mode of management and had satisfactory results, with temporary urine leaks resolving spontaneously in 4 patients, responding to temporary catheter diversion in 1 and requiring reoperation in 2. Plastic stents were inferior to silicone or rubber materials. Colon and/or bowel injury was universal and was not found to justify alteration in the choice of surgical timing or technique, or to influence over-all results. Adequately drained urine poses no threat of cicatrical stenosis. Excretory urography is reliable and retrograde studies are dependable when urography is equivocal.

A case is reported in which extensive mesocolonic and retroperitoneal granulomatous and fibrotic disease were apparently due to occult diverticulitis. The patient later had a good result from aggressive but limited operation for obstructions of the ureter and colon.

From a review of the literature and detailed study of 16 cases, the authors believe that ureteral obstruction in diverticulitis is more common than is apparent from the literature. They suggest that urograms be performed preoperatively in patients destined to undergo intestinal surgery. Management of the intestinal disease need not be altered from that initially planned for treatment of diverticulitis except with the proviso that the retroperitoneum be examined for the presence of a fibrotic inflammatory reaction. If this is found, they suggest that ureterolysis of the involved ureter be performed to allow relief of this obstruction.

Twelve years after adnexectomy, performed for actinomycosis of the left ovary, a 32-year-old woman developed abdominal and back pain. A solid tumour was palpated in the left lower abdomen. Colon contrast examination revealed a subtotal stenosis in the sigmoid colon, while sonography showed a complete stenosis of the left ureter with left hydronephrosis. Relaparotomy demonstrated a stone-hard tumour at the rectosigmoid junction, which involved the right ovary and ureter, as well as having infiltrated the retroperitoneum, predominantly on the left. After resection of the sigmoid colon, uterus and right ovary, as well as of the ureteric stenosis with reanastomosis, the further course was without complication. Histological examination confirmed actinomycosis of the left ovary, sigmoid colon and pelvic mesocolon. Therapy with amoxycillin, 500 mg three times daily, was started. As the patient had worn an intrauterine pessary for several years, primary infection of the uterus with spread into the abdominal cavity via tube and ovaries is likely to have been the course of events. The recurrence was probably caused by reactivation of residual actinomycetes in the retroperitoneum and pelvic mesocolon.

Abdominal actinomycosis is a rare chronic infectious disease, which may mimic abdominal cancer, inflammatory bowel disease or diverticulitis. We report the case of a 46-year-old women with a large bowel obstruction caused by extensive abdominal actinomycosis. Colon contrast examination revealed a stenosis in the sigmoid colon, while abdominal ultrasound showed a stenosis of the left ureter with left hydronephrosis. Preoperative presumptive diagnosis was a carcinoma of the sigmoid colon. She required emergency surgery, which involved both resection and colostomy. As in most cases reported in the literature, diagnosis was made postoperatively. Pathological examination following the sigmoid colon resection surprisingly revealed an actinomycosis. This case illustrates that consideration of actinomycosis in women with bowel obstruction and prolonged use of an intrauterine device could help to improve the preoperative diagnosis of this rare disease.
