Surgical management of stricture urethra in patients with chronic renal failure: Ten years' experience at a tertiary center

Abstract

Introduction: Patients suffering from stricture urethra and deranged renal function have poor quality of life. The incidence of urethral stricture co-existing with renal failure is comparatively small and cause may be multifactorial. There is paucity of literature on management of urethral stricture associated with deranged renal function. We present our experience of managing stricture urethra associated with chronic renal failure.

Materials and methods: This was a retrospective study conducted from 2010 to 2019. Patients with stricture urethra and deranged renal function (serum creatinine >1.5 mg/dl) who underwent urethroplasty or perineal urethrostomy were included in our study. A total of 47 patients met the inclusion criteria and were included in this study. Patients were followed every 3 months in their 1^st year of surgery and 6 monthly thereafter. Statistical analysis was done using SPSS version 16.

Results: There was a significant increase in the mean postopérative maximum and average urinary flow rates when compared to the preoperative values. The overall success rate was 76.59%. Out of 47 patients, 10 had wound infection and delayed wound healing, 2 patients developed ventricular arrhythmias, 6 patients developed fluid and electrolyte imbalance, 2 patients developed seizures, and 1 patient developed septicemia in the postoperative period.

Conclusion: Prevalence of patients with chronic renal failure associated with stricture urethra was 4.58% and features suggestive of deranged renal function at presentation were present in 1.81% patients. In the present study, complications related with chronic renal failure occurred in 17 (36.17%) patients. Multidisciplinary care of the patient along with appropriate surgical management is a viable option in this sub-group of patients.
