Abstract
INTRODUCTION: The aim of this study was to independently evaluate idiopathic urinary retention and other known Fowler's syndrome (FS) descriptions in 24 women treated for posterior fornix syndrome (PFS) by reinforcement of the uterosacral ligaments (USL) using the tissue fixation system (TFS). MATERIAL AND METHODS: The main inclusion criterion was: idiopathic urinary retention with post-void residual urines (PVR) >100 ml. RESULTS: The mean patient age was 63 years (range 32-87). Except for peak urine flow, features typical of FS were statistically improved (p 0.015 to <0.0001), pre-op mean with post-op mean in brackets: PVR 272 ml (34 ml); abnormal emptying symptoms n = 24 (18/24 cured or 80% improved); natural bladder volume 598 ml (301 ml); emptying time 50 seconds (20 seconds): peak flow 42 ml/sec (37 ml/sec); chronic pelvic pain n = 18 (14/18 >80% improved); maximal urethral closure pressure >90 cm (n = 4) 93 cm H(2)O (75 cm); frequency (14/14 improved); nocturia 110 episodes (33 episodes). CONCLUSIONS: Functional disorders typical of FS, also present in posterior fornix syndrome, principally idiopathic urinary retention, were cured/improved by USL sling repair. Suggested anatomical pathway: lax USLs weaken the backward muscular forces, unbalancing bladder neck and urethral closure. Compensatory forward-acting closure muscles narrow the distal urethra, causing urinary flow difficulties, and retention. This functional imbalance can be relieved by posterior sling repair. We suggest that, rather than spasm from the (weak) rhabdosphincter (Fowler's syndrome), USL weakness is the most likely cause of idiopathic urinary retention in women.
