Abstract

AIMS:

This ICI-RS report aims to analyze morphological or functional complications of the lower or upper urinary tract in elderly men, clarify the association between complications and benign prostatic obstruction (BPO) and define men who will develop these complications. Research proposals to further enlighten these associations were to be defined.

METHODS:

A think-tank discussion was held on the annual ICI-RS meeting in 2011. The published literature between 1966 and 2011 was reviewed and research proposals were defined with all congress participants.

RESULTS:

Post-void residual, bladder diverticula or calculi, vesico-ureteral reflux, hydronephrosis, renal insufficiency, and urinary retention appear with greater prevalence in patients with symptoms or signs of benign prostatic hyperplasia. BPO may directly or indirectly be responsible for these complications but conclusive evidence for BPO as the primary cause does not exist. Many of the complications have a multifactorial etiology and BPO is only partially responsible. It is currently impossible to define men who will develop complications.

CONCLUSIONS:

In contrast to the widespread belief of urologist, there is only rudimentary data available showing no convincing association between urinary tract complications and BPO. The ICI-RS proposes that prospective trials are conducted to demonstrate the association between complications and BPO by using cystometry, pressure-flow (P/F) studies, and other commonly used BPO parameters in men with complications and comparing those with a cohort of age-matched men without complications. Non-invasive proxy parameters of BPO, for example, ultrasonic measurement of detrusor wall thickness, can be used instead of P/F studies especially in longitudinal trials.
