G. Guazzoni et al., PROSTATIC SPIRAL VERSUS PROSTATIC UROLUME WALLSTENT FOR URINARY RETENTION DUE TO BENIGN PROSTATIC HYPERPLASIA - A LONG-TERM COMPARATIVE-STUDY, European urology, 24(3), 1993, pp. 332-336
Thirty-eight high-risk surgical patients with urinary retention due to
benign prostatic hyperplasia (BPH) were treated by placement of a pro
static spiral under local anesthesia (group 1: 20 patients) or a prost
atic stent under intravenous sedation (group 2: 18 patients). At the 1
-year follow-up, mean peak flow rate, residual urine volume and subjec
tive symptoms scale were significantly better in the stent group (p <
0.01). The rate of postoperative urinary incontinence and dislocation
of the device was greater in the spiral group. Cystoscopic manipulatio
n and removal of the device were definitely easier with the spiral. Bo
th the prostatic spiral and stent have specific roles in the treatment
of urinary retention in the unfit BPH patient. The selection of the m
ost suitable device depends on accurate patient assessment.
