Urinary Retention After Laparoscopic Definitive Surgery for Stages III and IV Endometriosis Without Explicit Nerve-Sparing Techniques: A Retrospective Analysis
Bibliographic record
Abstract
Objective: This research was conducted to characterize the prevalence and outcomes of postoperative urinary retention (POUR) after laparoscopic hysterectomy (LH) for definitive surgical management of stages III and IV endometriosis without an explicit nerve-sparing (NS) technique. Materials and Methods: This was a retrospective chart review of 106 cases from a single institution of patients who underwent LH for severe endometriosis without an explicit NS technique between March 2014 and August 2020. Six cases were excluded for concurrent low anterior–bowel resection, laparotomy, or incomplete charting. Results: The primary outcome was persistent POUR, defined in this study as continued need for catherization and self-reported sensation of POUR at ∼6 weeks postoperatively. At this time, 5/100 (5.0%) patients met the criteria for persistent POUR, of which 1/100 (1.0%) had objective evidence of retention requiring further management. Immediate POUR was present in 19/100 (19%) of patients. Only 5/100 (5.0%) required continued catheterization past discharge. No patients required catherization at 6 weeks. Conclusions: In nonexplicit NS LH for severe endometriosis, POUR is transient and rarely requires post-discharge catheterization. This study highlights a need for more investigation comparing conventional and NS techniques for reducing POUR after definitive laparoscopic surgery for advanced-stage endometriosis.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
