Endometriosis affecting the urinary tract: long-term outcomes and kidney function

Official title: Deep Endometriosis Affecting the Urogenital Tract: Long-term Outcomes and Impact on Renal Function

Run by Charles University, Czech Republic · NCT07776574 · Data updated 2026-11-12

This study looks at how deep endometriosis that touches the urinary tract affects the kidneys over time in adults with hydronephrosis or ureteral blockage.

Is this trial a fit for you?

Likely a good fit

Adults aged 18 and older with hydronephrosis or significant ureteral stenosis due to deep endometriosis, including those with prior ureteral surgery at the center.

Probably not a fit

Individuals without ureteral involvement from endometriosis or without renal impairment are less likely to experience direct kidney-related insights from this study.

What this trial studies

This observational study follows adults with deep endometriosis involving the urinary tract to understand long-term outcomes and changes in renal function. Participants are grouped based on surgical history and current need for surgery due to hydronephrosis or ureteral stenosis. The study collects data on kidney function, anatomy, and patient outcomes to better inform treatment decisions for ureteral endometriosis. No interventional treatment is specified in the protocol beyond observational assessments. The lead sponsor is Charles University in the Czech Republic, with data collected at General University Hospital in Prague.

Why it matters

Potential benefit: Findings could improve understanding of kidney outcomes in deep endometriosis affecting the urinary tract and guide future management strategies.

How similar studies have gone: Prior research has linked deep endometriosis with urinary tract involvement and renal impact; this study adds long-term observational data in a specific surgical-history stratified cohort.

Who can join: the full rules

Show full inclusion / exclusion criteria
Inclusion Criteria:• age ≥ 18 years;

* hydronephrosis caused by DE-related ureteral stenosis;
* for Group F: a history of surgical treatment of ureteral endometriosis (ureterolysis, ureteroureterostomy, UCNA) at our center at least 24 months previously;
* for Group S: indication for surgical treatment because of hydronephrosis or clinically significant ureteral stenosis;
* signed informed consent.

Exclusion Criteria:• pregnancy;

* malignancy;
* congenital uropathy;
* other renal diseases;
* inability to undergo dynamic renal scintigraphy (e.g., allergy to the radiopharmaceutical or severe comorbidities precluding the examination);
* previous urinary tract surgery unrelated to ureteral endometriosis that could substantially confound the assessment of renal function.
