Background And Purpose: Potassium-titanyl-phosphate (KTP) laser photoselective vaporization prostatectomy (PVP) is a relatively new technology for the management of lower urinary-tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). We review our initial experience.

Patients And Methods: We prospectively evaluated our initial 12-month experience with 80 W KTP laser PVP.

Background And Objectives: We evaluated the incidence of tumor recurrence following hand-assisted laparoscopic nephroureterectomy (HALNU) for the treatment of upper tract urothelial carcinoma.

Methods: The medical records of consecutive patients who underwent HALNU by a single surgeon (CW) between October 2001 and May 2005 were reviewed. The ureter was clipped before kidney dissection to prevent distal migration of tumor.

Background And Objective: Laparoscopic dismembered pyeloplasty for correction of ureteropelvic junction obstruction (UPJO) in the pediatric population is comparable to open dismembered pyeloplasty in success rates. Experience with this procedure however remains limited. We review our experience with this technique.

Objectives: 5 Alpha-reductase inhibitors (5ARIs) reduce angiogenesis in benign prostatic tissue. This has been postulated to affect the efficiency of the potassium-titanyl-phosphate (KTP) laser during photoselective vaporization prostatectomy (PVP), which has hemoglobin as its primary chromophore. We evaluate KTP laser PVP as treatment for benign prostatic hyperplasia (BPH) in patients on long-term 5ARIs.

Background And Purpose: Patients with urinary diversions are at higher risk for bladder urolithiasis. Often, the stone burden is large, necessitating open stone removal. We describe our technique for removing such stones using a combination of laparoscopic and endourologic instrumentation.

Background And Purpose: Transabdominal transvesical repair has been the standard treatment for difficult vesicovaginal fistulae. We describe a laparoscopic transvesical technique that minimizes operative morbidity while adhering to the principles of transabdominal repair as described by O'Conner.

Technique: The patient is placed in the lithotomy position using Allen stirrups, and bilateral 5F open-ended ureteral catheters are placed cystoscopically.

Purpose: Urinary and sexual functions were assessed in post-pubescent boys who had undergone 2-stage hypospadias repair in infancy for severe hypospadias with chordee.

Materials And Methods: A total of 44 boys who had undergone 2-stage hypospadias repair from 1985 to 1993 and who were at least 13 years old were contacted. Of the 44 boys 27 (61%) with an average age of 15.
