Introduction: The transurethral resection of the prostate (TURP) is the sta
ndard operation of patients with benign prostatic hyperplasia (BPH). Urinar
y incontinence after TURP is reported with a mean incidence of 2.1%. Detrus
or instabilities appear in approximately 60% of the patients before and in
26% after TURP. It may be presumed that elimination of detrusor instabiliti
es might improve continence. The aim of the study was to determine the alte
ration of continence after TURP.
Patients and methods: After a mean follow-up of 43 months (11.1 - 91.2) 99
patients (mean age 68 years) answered a questionnaire in which they recorde
d the continence status pre- and postoperatively as well as the subjective
changes of urinary continence using a Global Subjective Assessment Instrume
nt with linear analogue scale (reaching from -100% to + 100%). The data of
the questionnaire, age, follow-up time and the parameters of the preoperati
ve urodynamic assessment were evaluated statistically.
Results: Before TURP, 22.2% of the patients and after TURP, 12.1% of the pa
tients were incontinent. Only 2% of the patients reported urinary incontine
nce after TURP for the first time, while 12.1% became continent. 75.8% rema
ined continent and 10.1% remained incontinent. Using the linear analogue sc
ale, 56% of all patients indicated improved continence, 25% felt no change,
and 19% reported about a deterioration of continence (mean change of subje
ctive outcome + 21%). Only the status of renewed and sustained continence w
as associated with subjective improvement of continence (p < 0.01, mean cha
nge of subjective continence + 75% and + 17%, respectively). The subjective
change of continence showed no correlation with the age of the patients (p
= 0.54), duration of the follow-up period (p = 0.36) or subvesical obstruc
tion (p = 0.378).
Conclusions: The majority of patients report subjectively improved urinary
continence after TURP. Urinary incontinence appears in 2% after TURP, but i
ncontinence ceased in 12.1%.
