Clinical features and long-term surgical outcomes of ureteral endometriosis with hydroureteronephrosis: a retrospective study.
Article in BMC women's health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundUreteral endometriosis with hydroureteronephrosis can impair renal function, yet few clear guidelines exist for its surgical treatment. This study aimed to compare the clinicopathological features between patients undergoing ureterolysis with nodule excision versus segmental ureterectomy with anastomosis for ureteral endometriosis with hydroureteronephrosis, and to report the postoperative outcomes.
methodsThis retrospective study included 74 patients with ureteral endometriosis and hydroureteronephrosis who underwent surgery at a tertiary hospital between 2004 and 2024. Clinicopathological characteristics were compared between the ureterolysis and segmental ureterectomy groups using Student's t-test or Mann-Whitney U test for continuous variables, and the χ² test or Fisher's exact test for categorical variables. Variables with P < 0.05 on between-group comparisons were entered into a multivariable logistic regression analysis. Surgical outcomes, including recurrence of hydroureteronephrosis and ureteral complications, were reported.
resultsAmong the 74 patients, 25.7% presented with urinary symptoms. All patients had additional pelvic endometriosis beyond ureteral involvement, including ovarian endometriomas (75.7%) and deep endometriosis at other sites (82.4%). Ureteral endometriosis was classified as extrinsic (82.4%) or intrinsic (17.6%). 54 (73%) patients underwent ureterolysis with nodule excision and 20 (27%) underwent segmental ureterectomy with anastomosis. All 13 intrinsic lesions underwent segmental ureterectomy (P < 0.001). Multivariable analysis revealed that previous endometriosis surgery (OR = 4.413; 95%CI: 1.138-17.108; P = 0.032) and preoperative failed Double-J stenting (OR = 7.833; 95%CI: 1.946-31.522; P = 0.004) were independently associated with the segmental ureterectomy. At a median follow-up of 9 years, the ureterolysis group had 7.4% recurrent hydroureteronephrosis and 1.9% ureteral fistula; the segmental ureterectomy group experienced no recurrent hydroureteronephrosis or ureteral complications.
conclusionsUreteral endometriosis complicated by hydroureteronephrosis often lacks urinary symptoms, with only a minority of lesions classified as intrinsic subtypes, and is almost always accompanied by ovarian endometriomas or deep endometriosis at other pelvic sites. After careful patient selection, 73% of subjects underwent ureterolysis with nodule excision and demonstrated acceptable long-term outcomes. Segmental ureterectomy with anastomosis was reserved for refractory cases, such as patients with intrinsic ureteral lesions, a history of prior endometriosis surgery, or failed preoperative Double-J stenting.
