Left ileal conduit: A case report

Bladder cancer with urinary diversion by a sigmoid colon conduit after transverse colon stoma

Introduction

Sigmoid conduit is one of the methods for achieving urinary diversion, but it is performed less frequently than ileal conduit and ureterostomy. Herein, we report a case in which a sigmoid colon conduit was performed after nephrostomy and transverse colostomy.

Case presentation

A 70-year-old man was referred to our hospital because of a bladder tumor. Computed tomography and transurethral biopsy revealed advanced bladder cancer with ureteral and rectal invasion. Despite drug therapy, the tumor progressed. Thus, nephrostomy and transverse colostomy were performed for urinary and fecal diversion, respectively. Subsequently, chemotherapy was administered for 8 months. As nephrostomy-related complications occurred frequently during chemotherapy, a sigmoid colon conduit was performed instead of nephrostomy for urinary diversion to improve the patient's quality of life.

Conclusion

In patients with advanced bladder cancer requiring a double stoma of the urinary and fecal tracts, sigmoid colon conduit may be selected as a urinary diversion method.

A Modified Left Ileal Conduit in the Presence of a Left Short Ureter Following an Urgent Radical Cystectomy: A Case Report

The ileal conduit is the most common method performed for urinary diversion following radical cystectomy. The prepared conduit is usually placed on the right abdominal wall. There is not enough experience and literature on left-sided ileal conduits. Here, we report a case of a left-sided ileal conduit with a modified method and describe the surgical technique. A 68-year-old male patient had undergone an urgent radical cystectomy operation one year ago due to bladder cancer and gross hematuria. However, urinary diversion was not performed, and a bilateral nephrostomy was inserted. An ileal conduit was planned for the patient after oncological stabilization. On preoperative evaluations, bilateral ureters were observed to be short, with the left being prominent. The prepared ileal conduit was passed under the sigmoid mesentery due to the short ureters and placed on the left abdominal wall. There were no major complications during follow-ups. We emphasize that the method we performed is a safe option in mandatory situations.
