To evaluate the diagnostic utility of free prostate specific antigen (fPSA), alpha-1- antichymotrypsin-bound PSA (PSA-ACT), complexed PSA (cPSA), and including their associated ratios to total PSA (tPSA) in serum for discrimination between prostate cancer (PCa) and benign prostatic hyperplasia (BPH). ⋯ The determination of PSA-ACT or cPSA and the associated ratios do not improve the diagnostic impact to discriminate between PCa and BPH compared to fPSA/tPSA ratio. The ratios PSA-ACT/tPSA or cPSA/tPSA can be considered to be alternative tools of fPSA/tPSA.

Randomized Controlled Trial Comparative Study Clinical Trial
Sacral root neuromodulation in the treatment of refractory urinary urge incontinence: a prospective randomized clinical trial.
To compare the effectiveness of sacral root neuromodulation with that of conservative management in ameliorating symptoms of refractory urinary urge incontinence and enhancing quality of life, to assess the objective response to neuromodulation as revealed by urodynamic testing, and to delineate the long-term outcomes of neuromodulation. ⋯ Neuromodulation is markedly more effective than conservative management in alleviating symptoms of refractory urge incontinence. Quality of life and urodynamic function are also improved by neuromodulation. The effects of neuromodulation are long-lasting, and associated morbidity is low.

Treatment of superficial bladder tumors: achievements and needs. The EORTC Genitourinary Group.
The therapeutic objectives in the initial treatment of superficial tumors are to remove completely the tumor, to assess the need for further therapy and to plan the follow-up. ⋯ Investigation of the concept of chemoimmunotherapy up to now lacked evidence of advantages for this approach. Preventive regulatory measures directed to decrease tobacco smoking and some occupational exposures to aromatic amines may contribute to the reduction of bladder cancer. Bladder cancer is a multistep process making this tumor a candidate for chemoprevention. To date, retinoids are the best-studied chemopreventive agents achieving mixed clinical results in superficial bladder tumors. The potent apoptosis-inducing retinoid fenretinide is currently in the phase III trials. The follow-up of patients with all types of superficial tumors must be lifelong; unfortunately cystoscopy cannot be replaced yet by the control of any markers present or not in the urine. There is hope this may change in the near future.

A nonpalpable testis was the first indication for laparoscopy in urology. This primarily diagnostic procedure has evolved to complete laparoscopic orchidopexy. An associated inguinal hernia due to an open processus vaginalis is reported in 26% of cryptorchidism cases. Simultaneous laparoscopic orchidopexy and herniorrhaphy are therefore the next logical step. ⋯ Laparoscopic dissection of the internal inguinal ring allows perfect delineation of the anatomic structures and their relationship. Transection of the processus vaginalis can be performed without disturbance of the inguinal canal. Hernias can be closed with essentially the same technique as used in open surgery. Morbidity was minimal in all patients.

Comparative Study Clinical Trial
Influence of carbon dioxide on respiratory function during posterior retroperitoneoscopic adrenalectomy in prone position.
To evaluate the influences of CO(2) insufflation on changes in blood gas analysis and end tidal CO(2) tension (PetCO(2)) during posterior retroperitoneoscopic adrenalectomy in the prone position. ⋯ Transperitoneal absorption of CO(2) occurs in patients undergoing retroperitoneoscopy in the prone position. The alveolo-arterial CO(2) gradient may be the only parameter which indicates the absorption of CO(2) during PRA.
