Impacts of Bariatric Surgery on Improvement of Incontinence Among Obese Asian Women: A Prospective Study and Literature Review

INTRODUCTION

Limited studies investigate bariatric surgery's role in improving UI status among Asians, specifically Middle Eastern Asian women. The aim of this study is to investigate the effect of bariatric surgery on the three most prevalent urine incontinence (UI).We also reviewed the current literature exploring the studies performed in Asian countries.

MATERIALS AND METHODS

A total of 77 women out of 200 who had UI and indications for bariatric surgery completed demographic information and the questionnaire (QUID) prior to surgery and 6 months after the surgery. For statistical analysis, the Mann-Whitney U test, Wilcoxon test, and Friedman test were utilized. We also performed a literature review with the aim of investigating studies performed in Asian countries.

RESULTS

Among the initial analysis of 200 participants, 50.5% reported UI symptoms before surgery. The average weight loss was 29 kg, with a standard deviation of 7 kg. The mean BMI dropped 11.2 kg/m2, and the standard deviation was 2.5 after weight loss. Post-surgery, significant reductions in UI scores were observed across all severity levels, with a notable 44% achieving complete symptom resolution, indicating a substantial decrease in urinary incontinence. Stress, urine incontinence, and mixed urine incontinence symptoms had improved in 75%, 71%, and 30% of women, respectively. Notably, age and gynecological history were identified as critical factors influencing the extent of UI improvement.

CONCLUSION

This study reveals significant improvements in urinary incontinence scores, with age and gynecological history playing pivotal roles in UI improvement.

Pediatric Pyeloplasty in the Poor Function Kidneys: Does Surgical Success Guarantee Improvement in Renal Function? Single-Center Experience and Review of Literature

PURPOSE

To investigate the effect of pyeloplasty in pediatric patients with poor function kidneys, focusing on the split renal function (SRF) and anteroposterior diameter (APD) of the renal pelvis.

MATERIALS AND METHODS

A retrospective study included 47 pediatric patients with ureteropelvic junction obstruction (UPJO) who underwent open pyeloplasty with SRF< 20%. All patients were recruited from the Labbafinejad University Hospital center from April 2014 to October 2020. The results of preoperative ultrasonography and Diethylenetriamine pentaacetate (DTPA) scan compared with the results of the ultrasonography and DTPA scan 6 months and one year after surgery. Finally, Wilcoxon signed-rank test was used to test differences the SPSS (version 25) software statistical computer package.

RESULTS

The mean age of participants was 1.5 years. There were 34 cases with SRF between 10% and 20%, and 13 cases with SRF < 10%. The findings showed that pyeloplasty for UPJO leads to a significant improvement in renal function in poorly functioning renal units with 10% ≤ SRF < 20%. Although improvement in renal function occurred in the group with SRF of less than 10%, it was not statistically significant. The APD in both groups was statistically significantly improved. No correlation between genders and outcomes was found.

CONCLUSION

Poorly functioning renal unit (SRF < 20%) can show functional improvement after the pyeloplasty.
