# Type I Ureteral Triplication in an Adult Associated With an Obstructed Extravesicular Megaureter Surgically Managed With Partial Nephrectomy

## TL;DR

A rare case of a complete ureteral triplication in an adult was successfully treated with partial nephrectomy, resolving pain and infections.

## Contribution

This case report presents a novel surgical management approach for a rare congenital urinary tract anomaly in an adult.

## Key findings

- Partial nephrectomy resolved the patient's flank pain and recurrent urinary tract infections.
- The surgical approach avoided more invasive procedures and preserved functional urinary anatomy.
- The case highlights the efficacy of partial nephrectomy in managing obstructed megaureter in adults.

## Abstract

A complete ureteral triplication is a rare congenital urinary tract anomaly that typically presents in childhood. This is an exceedingly rare case of an adult male presenting with right pyelonephritis and flank pain who was subsequently diagnosed with a right type I ureteral triplication associated with an obstructed megaureter inserted into the prostatic urethra. This patient underwent a right partial nephrectomy to remove the dilated and non-functional upper renal segment leaving behind a blind ending ureteral remnant. Following partial nephrectomy, the patient's flank pain and recurrent urinary tract infections resolved despite persistent dilation of the ureteral remnant. While a standard method of surgical management for a triplicated ureter has not been well established in the adult population, in this case, partial nephrectomy has demonstrated efficacy while avoiding more invasive procedures.
