Psychosocial mechanisms of a behavioral treatment for urinary incontinence of prostate cancer survivors

Abstract

Purpose: We examined underlying psychosocial processes of a behavioral treatment for urinary incontinence (UI) of prostate cancer survivors.

Design: Secondary analysis of data collected from a clinical trial.

Sample: Two hundred forty-four prostate cancer survivors who participated in a clinical trial of behavioral intervention to UI as intervention or control subjects.

Methods: The participants had a 3-month behavioral intervention or usual care and were followed up for an additional 3?months. They were assessed at baseline, 3, and 6?months. Latent growth curve models were performed to examine trajectories of each study variable and relationships among the variables.

Findings: Increasing self-efficacy and social support were significantly and independently associated with more reduction of urinary leakage frequency over time.

Implications for psychosocial oncology: Providing problem-solving skills and social support, including peer support, are essential for empowering patients to reduce UI.     

部分胃体-窦部代膀胱术的临床应用及长期随访

目的探讨部分胃体-窦部代膀胱术的临床应用价值。方法回顾性分析30例胃代膀胱术患者的临床资料、实验室检查、影像学检查、膀胱镜及尿动力学检查结果。男17例，女13例。年龄21—69岁，平均55岁。原发病为膀胱癌24例，结核性膀胱挛缩6例。结果术后新膀胱贮尿功能良好，患者经尿道排尿，膀胱容量280—580ml，平均385ml；最大尿道压20—60cm H2O，平均49cm H2O；充盈期膀胱压5—15cm H2O，平均12cmH2O；最大膀胱压35—65cm H2O，平均55cmH2O；排尿期最大膀胱压28—60cm H2O，平均46cm H2O；最大尿流率10～28ml／s，平均18ml／s；剩余尿量5～85ml，平均20ml。随访9个月一24年，平均8．2年，无水、电解质代谢紊乱，无输尿管返流，无尿失禁及肾功能损害。4例出现会阴部、膀胱区疼痛；5例出现遗尿，术后3—6个月逐渐缓解；1例因膀胱结石再次手术。术后3．5年膀胱肿瘤复发1例，行经尿道膀胱肿瘤电切术。结论部分胃体一窦部代膀胱术后并发症少，相关生理指标接近正常。     

Postpartum urinary incontinence: a comparison of vaginal delivery, elective, and emergent cesarean section

The aim of this study was to assess the impact of delivery on the pelvic floor and whether cesarean section (C/S) can prevent pelvic floor injury. Five hundred thirty nine women were divided into three groups according to the delivery method adopted: elective C/S, emergent C/S, and vaginal delivery. A urinary incontinence questionnaire survey was conducted around 1 year postpartum. Emergent C/S may be a major risk factor for postpartum urinary incontinence and interfere with the benefit of elective C/S for preventing pelvic floor injury. Hence, not all C/S deliveries can reduce the likelihood of postpartum urinary incontinence. The key lies in whether the C/S is performed before labor.
