Purpose: Data regarding the treatment of ureteropelvic junction obstruction (UPJO) in horseshoe kidneys are limited. We performed a retrospective analysis of our experience with minimally invasive treatment of UPJO in patients with this anomaly.
Methods: Between March of 1996 and March 2008, 9 patients with horseshoe kidneys were treated for UPJO at our institution.
Purpose: The minimally invasive treatment of ureteropelvic junction obstruction has evolved during the last decade from endoscopic to laparoscopic and robotic. We review our 10-year experience with ureteropelvic junction obstruction, and report on our experience and followup.
Materials And Methods: We reviewed all patients treated during the last 10 years.
Background And Purpose: Since first being described in 1993, laparoscopic pyeloplasty has proven to be less morbid but equally as effective as open pyeloplasty. The technical complexity of the procedure, however, has made it difficult for many surgeons to adopt. The da Vinci robot-assisted laparoscopic pyeloplasty (RP) was introduced to shorten the learning curve.

Patients And Methods: We reviewed all pediatric laparoscopy cases performed by a single surgeon from 1996 to 2003. There were 257 patients ranging in age from 4 months to 19 years.
Objectives: To construct a pre-biopsy predictive model incorporating several clinical variables, including African-American (AA) or Caucasian race, to predict the risk of prostate cancer detection on prostate biopsy, as traditionally AA men have had a higher incidence of prostate cancer than Caucasian men, but previous predictive tools for prostate cancer have not incorporated the effect of race.
Patients And Methods: We evaluated 9473 patients undergoing initial prostate biopsy at three equal-access healthcare institutes from 1993 to 2003. At each biopsy session, patient age, race, serum prostate-specific antigen level (PSA), digital rectal examination (DRE) findings, number of biopsy cores taken, year of biopsy, and pathological findings were recorded.
Purpose: High grade intraepithelial neoplasia and atypical small acinar proliferation increase the probability of cancer on a subsequent prostate biopsy. We investigated whether race is prognostic for detecting cancer in patients undergoing repeat prostate biopsies.
Materials And Methods: At a single institution 416 men underwent 2 or more prostate biopsies from January 1993 through June 2003 for a total of 1,023 biopsies.
Purpose: Population studies link increased BMI with an increased risk of cancer and cancer mortality and in particular a greater risk of RCC. We evaluated the impact of BMI and other clinical/pathological characteristics on survival in patients with RCC treated with radical or partial nephrectomy.
Materials And Methods: Between 1995 and 2003 patients undergoing radical (760) or partial (399) nephrectomy for RCC were entered into a database.
Purpose: We reported a nomogram and subsequently a corrected version for predicting the probability of positive biopsy in men with 1 or more prior negative biopsies. In this study we assessed the validity of this nomogram when applied to an external dataset.
Materials And Methods: There were 230 patients from the Brooklyn Veterans Administration Medical Center who underwent 1 or more repeat biopsies after initial negative biopsy from January 1993 to June 2003.
