“…A record of psychiatric disorders, such as PTSD, enhanced the chances of successful first-stage SNM by 3.92 times in women and 7.71 times in men who had previously undergone transurethral resection of the prostate. Meanwhile, for each 10-year increase in age, SNM success rates decreased by 2.3-fold and 1.3-fold in men and women, respectively [129]. Another study found that patients with detrusor acontractility had significantly lower efficacy when undergoing SNM (p = 0.03).…”

Underactive bladder (UAB) is a prevalent but under-researched lower urinary tract symptom that typically occurs alongside detrusor underactivity (DU). Unlike UAB, DU is a urodynamic diagnosis which the International Continence Society (ICS) defines as “a contraction of reduced strength and/or duration, resulting in prolonged bladder emptying and/or a failure to achieve complete bladder emptying within a normal time span”. Despite the widespread prevalence of UAB/DU, there are significant gaps in our understanding of its pathophysiological mechanisms, diagnosis, and treatment compared with overactive bladder (OAB) and detrusor overactivity (DO). These gaps are such that clinicians regard UAB/DU as an incurable condition. In recent years, the understanding of UAB has increased. The definition of UAB has been clarified, and the diagnostic criteria for DU have been considered more comprehensively. Meanwhile, a number of non-invasive diagnostic methods have also been reported. Clinical trials involving novel drugs, electrical stimulation, and stem cell therapy have shown promising results. Therefore, this review summarizes recent reports on UAB and DU and highlights the latest advances in their diagnosis and treatment.

Zusammenfassung Die Ätiologie der neurogenen, nicht-obstruktiven Harnretention ist mannigfaltig. Neben zentralnervösen Erkrankungen kommen auch Erkrankungen des peripheren Nervensystems in Betracht. Die Restharnbildung kann zu erheblichen Problemen führen, die die Patient*innen in ihrem täglichen Leben enorm beeinflussen können. Nur eine differenzierte Diagnostik macht eine der Harnblasenfunktionsstörung und auch der Lebenssituation der Patient*innen angepasste Therapie möglich. Sowohl konservative als auch operative therapeutische Strategien stehen zur Verfügung, medikamentöse Therapieansätze treten in den Hintergrund. Als kausale Therapie der Funktionsstörung sind insbesondere neuromodulative Verfahren geeignet. Wenn eine artifizielle Harnblasenentleerung notwendig wird, sollte der intermittierende Selbstkatheterismus wenn immer möglich einem Dauerkatheter vorgezogen werden.

“…51 Prior surgery for the BORRS (TURP or bladder neck incision) has been shown to improve the odds of success with SNS (odds ratio: 7.71, 95% confidence interval: 1.43-41.5). 54 Available evidence shows some factors that might predict responsiveness to BORRS. Older age might influence the outcome adversely.…”

AimsTo address the predictive factors of a successful voiding after bladder outflow resistance reduction surgery (BORRS) in men presenting with acute or chronic urinary retention (UR).MethodsA think tank (TT) of ICI‐RS was gathered in 2023, Bristol, UK, to discuss several aspects of the problem, such as the pathophysiology of UR, the clinical and urodynamic evaluation of men with UR and whether it is possible to predict which men will be able to successfully void after treatment with contemporary surgical options.ResultsThe TT agreed that successful voiding after BORRS depends on several factors but that a strong recommendation cannot be made regarding preoperative evaluation and whether there are predictive factors of success because of the heterogeneity of patients and methodology in published trials. The diagnosis of obstruction in men with UR may be challenging when there is apparent reduced detrusor contraction during urodynamic studies. Even in the absence of bladder contractility there is documentation of such cases that have voided adequately after BORRS. Still, detrusor underactivity and inadequate relief of prostatic obstruction are the main causes of an unsuccessful voiding after BORRS. Conventional resection and enucleation methods remain the most successful surgeries in relieving UR in men, whereas the efficacy of minimally invasive surgical treatments needs to be assessed further.ConclusionResearch is needed to understand the pathophysiology of UR and the predictors of successful voiding after different types of BORRS in men with UR.
