Suprapubic cystostomy during renal transplantation in a patient with a urethral stricture after hypospadias surgery: A case report

INTRODUCTION: Renal transplantation often causes polyuria, and a Foley catheter is typically placed after transplantation. A urethral stricture often makes it difficult to insert a normal diameter urethral catheter. CASE PRESENTATION: We report on the case of a 16‐year‐old adolescent male with a history of hypospadias surgery who underwent a cystostomy during renal transplantation. A cystostomy was placed during transplantation because of stricture of the pendulous urethra. Urine leakage into the retroperitoneum occurred after cystostomy catheter removal. An 8‐Fr urethral catheter was placed, and urine was aspirated to prevent drainage failure. Voiding cystourethrography performed after 2 weeks showed that there was no leakage. After that, the patient had no trouble with urination. CONCLUSION: A cystostomy may be one strategy for renal transplantation patients with a urethral stricture. Urine leak can occur because of the delay in wound healing caused by immunosuppressive therapy. Therefore, cystostomy management strategies should be considered carefully.
