#p value between the changes of the parameters after the 1st and repeat injections.

*p value <0.05 versus baseline (or before the injection therapy).

IPSS, International Prostate Symptom Score; IPSS-V, IPSS voiding subscore; IPSS-S: IPSS storage subscore; IPSS-T, total IPSS score; PPBC, Patient Perception of Bladder Condition score; QoL-I, quality of life index; CBC, cystometric bladder capacity; Pdet, detrusor voiding pressure; Qmax, maximal urinary flow rate; Vol., voided volume; PVR, post-void residual; VE, voiding efficiency.

Data are expressed as mean ± standard deviation.
