SubjectUMCN 3.1: Neuromuscular development and genetic disorders
Nearly one out of two Dutch married women experiences urine loss. Overactivity of the bladder can cause urine loss and frequent micturition. At the urology department of the UMC Nijmegen, Posterior Tibial Nerve Stimulation or PTNS to treat overactive bladder complaints was investigated. Also patients with voiding dysfunction were examined. 90 patients with overactive bladder complaints and 39 patients with voiding dysfunction were enrolled in the study. All patients received 12 weekly sessions in which a needle was placed three fingerbreadths above the medial ankle and connected to a low voltage stimulator for 30 minutes. 60-64% of the participants considered the treatment as successful and demanded maintenance therapy. Patients presented with less urine loss and less urinary frequency. 38% was even considered as continent. Urodynamic investigation confirmed increment of bladder capacity, a larger volume at which desire to void appears and more efficient bladder emptying. Quality of life parameters improved. No mayor side effects were seen. PTNS is minimally invasive treatment without serious side effects. Unfortunately a long term maintenance schedule is needed; therefore more investigation concerning the implantable stimulator is warranted
