Treatment of Urinary Tract Tuberculosis with Ureteral Stenosis and Hydronephrosis
Tuberculosis of the urinary tract can cause ureteral stricturing that obstructs urine outflow and leads to hydronephrosis. When this complication is present, management decisions extend beyond standard pharmacological treatment — the timing and nature of urological intervention are critical to kidney function preservation.
Clinical Scenario
Ureteral (urinary tract) stenosis caused by tuberculosis, with associated hydronephrosis. The obstructive lesion threatens ipsilateral kidney function and requires a structured approach to urinary drainage and — in selected cases — endoscopic intervention.
Approach Overview
The structured protocol for this scenario centres on early urological intervention — specifically urinary drainage — timed carefully in relation to the start of pharmacological treatment, with kidney function preservation as the primary driver. In a defined subset of patients with a particular stenosis profile, a specific endoscopic procedure may be attempted as an alternative to drainage alone.
Full intervention criteria, procedural details, and follow-up guidance are available in the complete structured protocol below.

- In the presence of ureteral stenosis due to tuberculosis, a double-J catheter or nephrostomy should be used early (up to 1 month), before the beginning of pharmacological treatment, in cases in which kidney function preservation is necessary (GRADE: moderate, strong).
- For patients with a single stenotic site measuring less than 2 cm through which it is possible to pass a guidewire, endoscopic treatment with balloon dilation or endoureterotomy followed by the insertion of a double-J catheter for 6 weeks can be attempted (success rate of up to 60%) (GRADE: low, weak).
