Introduction and hypothesis
To determine the clinical outcomes of adding a tension-releasing suture (TRS) appendage for manipulation of over-tensioned single-incision slings (SIS) as a means to relieve postoperative voiding dysfunction.
Methods
A retrospective observational study conducted from January 2010 to July 2017. The records of patients with urodynamic stress incontinence (USI) without needing concurrent procedures who underwent anti-incontinence surgery using MiniArc, Solyx, and Ajust with voiding dysfunction were collated and analyzed. The primary outcome measure was the recovery of normal post-void residual urine (PVR) after TRS manipulation. The secondary outcome measures were the pain intensity noted during manipulation (quantified by visual analog scale) and the continence rate [assessed by (1) objective cure: 1-h pad test weight < 2 g and absence of USI; (2) subjective cure index score ≤ 1 on question 3 of the UDI-6: “Urine leakage related to physical activity, coughing, or sneezing?”].
Results
There were 73 patients with high post-void residual (PVR) urine. The 42 (9.5%) patients with over-tensioned slings were managed with TRS manipulation while the 31 patients (7%) with high PVR and no sling over-tension were managed with intermittent catheterization. All patients in both groups regained normal PVR. The TRS-manipulated group demonstrated an objective cure rate of 92.9% (39/42) and subjective cure rate of 91% (38/42). Pain experienced during TRS manipulation was significantly higher with the Ajust system (p = 0.018). Three patients had persistence of USI, two with MiniArc and one with Solyx.
Conclusions
The TRS manipulation is a well-tolerated procedure that can effectively relieve voiding dysfunction for over-tensioned SIS without affecting continence cure rates.
