Determination of uPSA cannot differentiate BPH and CaP. However, in the group of pts. with proven localized CaP, uPSA can provide additional information concerning T-staging. Moreover, simultaneous monitoring of PSA and uPSA response on hormonal therapy, can provide an early recognition of androgen-indiferent CaP (AIPCA) and hormone-resistent CaP (HRPCA).

Although with some limitations, this mathematical model can explain the great variety of PSA serum concentrations in PCa patients.

Ureteral fistulae after kidney transplantation represent major early urological complications with reported incidence from 1.2% to 12% in large series. The aim of the study is to establish the incidence, types and ureteral fistula related morbidity and lethality rates, by donor type. From 1995. to 2001, a total of 224 kidney transplantations (171 from living and 53 from cadaveric donor) have been performed at the Institute of Urology and Nephrology in Belgrade. Mean patients age was 36,67 years (11-64; SD = 10.69). Ureteral fistulae appeared only after living donor transplantation in a total of five patients (2.2%) (p > 0.05). In all patients open fistula repair was performed. Two patients had recidive ureteral fistula after primary and after secondary open repair. Following the third open repair one patient had lethal outcome. Ureteral fistulae after kidney transplantation still remain challenging urological problem with considerable morbidity and lethality rates.

In the era of ESWL, PCNL and ureterorenoscopy, PCN-dissolution of urinary stones is rare procedure. However, this minimally invasive procedure could be successfully performed in selected cases.
