Re: Varicocele and male factor infertility treatment: A new meta-analysis and review of the role of varicocele repair

摘要

Purpose: We compared laparoscopic and robotic pyeloplasty to identify factors associated with procedural efficacy.Materials and Methods: We conducted a retrospective multicenter trial incorporating 865 cases from 15 centers. We collected perioperative data including anatomical and procedural factors. Failure was denned subjectively as pain that was unchanged or worse per medical records after surgery. Radiographic failure was defined as unchanged or worsening drainage on renal scans or worsening hydronephrosis on computerized tomography. Bivariate analyses were performed on all outcomes and multivariate analysis was used to assess factors associated with decreased freedom from secondary procedures.
