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.

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.

This video demonstrates a laparoscopic abdominal perineal resection for a fixed 4.8-cm mass involving the posterior and left rectal walls and left puborectalis, 2 cm from the anal verge (see Video, Supplemental Digital Content 1, http://links.lww.com/DCR/A127). We detail the steps of the procedure, all completed in lithotomy, including lateral-to-medial dissection; identification and protection of the left ureter and presacral nerves; division of the inferior mesenteric artery; medial-to-lateral dissection, with meeting the previous dissection plane; total mesorectal excision and pelvic dissection; perineal dissection and layered closure; and abdominal inspection and colostomy creation. Total operative time was 181 minutes. The specimen total mesorectal excision was complete with a negative circumferential radial margin (greater than 1 cm). Final pathology was T3N2M0.

Iatrogenic ureteral injury (IUI) is a dreaded complication of abdominopelvic surgery. Although rare, it is associated with severe consequences. This complication most commonly occurs during gynecological procedures but may also occur during colorectal surgeries. We present two cases of IUI in patients in whom the ureteric stents were electively placed. The first case was a 71-year-old male with no significant medical history. The patient underwent an elective laparoscopic sigmoidectomy for complicated diverticulitis. During the procedure, a proximal IUI occurred, and was recognized and repaired. The second case occurred in a 68-year-old male with a history of multiple complicated abdominal surgeries. The patient underwent a second redo low anterior resection for a long preanastomotic stricture. The IUI occurred in the right fibrosed presacral plane, approximately 3 cm proximal to the bladder. The ureter was reimplanted to the bladder during the same procedure. We will also present a literature review of IUI, including the risk factors, intraoperative prevention, and repair options.
