OBJECTIVE: To investigate the features of chronic prostatitis (CP) during puberty and the effects of biofeedback on young males with this disease.

PATIENTS AND METHODS: In all, 40 patients were divided into two groups; group 1 included 25 pubertal patients with CP (mean age 16.5 years, sd 1.1) and group 2 was a control group including 15 patients (mean age 16.2 years, sd 1.2) with a normal lower urinary tract. National Institute of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) scores (three parts) were assessed individually in both groups. Expressed prostatic secretions and urine samples after prostate massage from group 1 were cultured to determine whether patients were infected with bacteria, and group 1 was categorized into various NIH types. Each patients in the two groups underwent urodynamics and group 1 were treated with biofeedback.

RESULTS: In group 1, there were one, three and 21 patients with type II, IIIA and IIIB prostatitis. The incidence of staccato voiding and detrusor-sphincter dyssynergia (DSD), and the maximum urinary flow rate (Qmax), postvoid residual urine volume (PVR), maximum detrusor pressure (Pdetmax) and maximum urethral closure pressure (MUCP) between the groups were significantly different (P < 0.05). The total NIH-CPSI scores and all the subdomains between the groups before biofeedback were significantly different (P < 0.001). In group 1 the difference in NIH-CPSI scores and Qmax before and after biofeedback was significant (P < 0.05).

CONCLUSIONS: The main type of CP during puberty is IIIB; the dominating symptom is a voiding disorder. The impact on life and psychological effects are substantial. Pubertal boys with CP have pelvic floor dysfunction and several abnormal urodynamic values, i.e. staccato voiding, DSD, decreasing Qmax, and increasing Pdetmax and MUCP. The effect of biofeedback strategies for treating pubertal CP is satisfactory.
