Postoperative Reduction in Postvoid Residual Urine Volume May Be Associated With Bladder Capacity Decrease Rather Than an Increase in Tidal Voided Urine Volume in Patients With Pelvic Organ Prolapse.
Article in The journal of obstetrics and gynaecology research, 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
aimMore than half of patients with pelvic organ prolapse (POP) complain of lower urinary tract symptoms (LUTS), especially voiding difficulty. Surgical approaches such as laparoscopic sacrocolpopexy (LSC) and transvaginal mesh surgery (TVM) often result in improved voiding function in POP cases. The present study primarily aimed to evaluate postoperative longitudinal changes in bladder-related parameters after POP repair rather than determine superiority between surgical techniques.
methodsWe retrospectively evaluated 216 patients with POP treated with LSC or TVM at our hospital. LSC was used for 86 patients, and TVM for 130 patients. Preoperative bladder capacity (BC), voided urine volume (VV), and post-void residual urine volume (PVR) were recorded. The International Prostate Symptom Score (IPSS), quality of life (QOL) score, and 60-min pad weight testing were also used to assess QOL change in LUTS.
resultsBC significantly decreased 3, 6, and 12 months after LSC, and 6, 12 months after TVM. VV significantly declined 12 months after LSC but almost did not change compared with its preoperative value. PVR, IPSS, and QOL score significantly decreased 3-12 months postoperatively in both groups. Conversely, the rate of complications after surgery did not significantly differ between both groups. Comparison of preoperative condition and 1-year postoperative outcomes showed no significant differences in PVR, 60-min pad test, and IPSS plus QOL score.
conclusionsOur findings suggest that postoperative reduction in PVR may be associated with decreased BC at strong desire to void rather than increased tidal VV.
