Objective:
Overactive bladder (OAB) affects hundreds of millions of people worldwide and has significant detrimental effects on quality-of-life. Percutaneous tibial nerve stimulation (PTNS) is endorsed in the European guidelines of Urology as second-line therapy - on par with pharmacological treatment for women with OAB.
Methods:
This prospective cohort study describes our clinical experience with PTNS in a daily outpatient clinic, on a consecutive cohort. The cohort of 116 patients was mixed; including both men and women with idiopathic (iOAB) and neurogenic (nOAB) overactive bladder. Patients were treated with a 12-week course of PTNS followed by monthly maintenance treatment. Data were collected during 4 years.
Results:
The most common indication for PTNS was OAB with urge incontinence (53%) followed by OAB-dry and nocturia (both 16%). One hundred and ten (95%) patients completed follow-up and 68 patients (62%) continued to maintenance treatment. A total of 68 patients reported an effect on PROM, BD and ICIQ-OAB, which is the same 62% that continue in maintenance PTNS. A significant decline was seen in overall ICIQ-OAB score, with a median drop from 87 to 54, a significant decline in overall frequency and nocturia on bladder diary and a shift in pad test group in 19% of the incontinence patients.
Conclusion:
PTNS shows an equally significant effect on men as well as women both in the iOAB and nOAB subgroups in a daily outpatient clinic. In our opinion, PTNS should be a standard treatment option available at urological departments, where both men and women in both sub-groups could benefit from treatment. Further randomized studies focusing on men with iOAB are needed.
