Neuro-urology: functional disorders in male and female urogenital tract

Research is focused in the Pelvic Floor & Sexuality Research Group Leiden on bladder/urethral/pelvic floor (dys)function, sexual (dys)function) in men and women and on andrological aspects. With regard to neuro-anatomy and neuro physiology, a close relationship exists between those (dys)functions.

Aim and focus

Various studies are focused on:

  • Anatomy: neuro-anatomy of pelvic floor musculature and external sphincters in relation to neurostimulation [Voorham] and operative incontinence procedures and sexual (dys)function in women [Elzevier],
  • Neurophysiology: the mode of action and efficacy of various pelvic floor physiotherapeutic and/or electrical stimulation techniques [Voorham Lycklama à Nijeholt].
  • Validation and standardization of the measurement of pelvic floor function with the Multiple Array Probe Leiden (MAPLe) [Voorham, Pelger]
  • Innovative surgical techniques in male urinary stress incontinence [Elzevier]
  • The value of pelvic floor physiotherapy in post-prostatectomy incontinence [Voorham]
  • Prevalence of sexual dysfunction in urological patients [Elzevier]
  • Position in international context

In the last decade the urological research on bladder/pelvic floor (dys)function and sexual (dys)function has intensified. In international context, our approach, combining neuro-anatomy, neurophysiology and various innovative diagnostic and stimulation techniques in a clinical setting is quite unique.


In 2003 the Pelvic Floor & Sexuality Research Group Leiden was initiated at the dept of urology/pelvic floor center to facilitate related studies; within a few years the research group was on tract. Several studies are supported by unrestricted grants from Pfizer and Stichting Amsterdam 98.

Future themes

  • Studies related to the implementation of the Multiple Array Probe Leiden (MAPLe)
  • Preservation/improvement of sexual function and continence in relation to laparoscopic radical prostatectomy
  • Improvement of diagnostic and therapeutic pelvic floor physiotherapeutic and/or electrical stimulation techniques
  • Improvement of prevention and treatment of urinary stress incontinence in male and female patients
