: To evaluate the effect of concomitant hysterectomy on perioperative outcomes in patients who underwent obliterative pelvic organ prolapse (POP) surgery.

: This retrospective study included 95 consecutive patients with no prior hysterectomy who underwent obliterative surgery for POP between February 2015 and April 2021. Perioperative outcomes of colpocleisis without hysterectomy (C) and colpocleisis with hysterectomy (CH) were compared.

: Of the 95 patients, 49 (51.6%) underwent C and 46 (48.4%) underwent CH. Patient characteristics including age, body mass index and history of prolapse surgery were comparable between the groups (P-values .367, .199, and .363, respectively). The rate per prolapse stage, from stage 2 to stage 4, was similar in both groups (P-values .709, >.999, and .838 for Stage 2, Stage 3, and Stage 4, respectively). The mean operating time was shorter in the C group than in the CH group (68.9 ± 25.7 minutes versus 94.7 ± 23.1 minutes, P-value < .001). Other perioperative outcomes including postoperative hemoglobin drop, duration of Foley catheter, rate of intraoperative complications, rate of patients with postoperative adverse events, reintervention rate and readmission rate were comparable in both groups (P-values .125, .362, .484, > .999, .495, and > .999, respectively).

: CH is associated with a longer operative time compared to C. However, concomitant hysterectomy does not appear to affect perioperative outcomes other than the operative time negatively.
