Xanthogranulomatous pyelonephritis: a comparison of open and minimally-invasive surgical approaches.

To compare perioperative outcomes between patients undergoing minimally-invasive (MIS) and open surgical approaches for the treatment of Xanthogranulomatous Pyelonephritis (XGP). Between 2007 and 2017 we retrospectively identified 40 patients undergoing nephrectomy at our institution for pathologically confirmed XGP. Patients whose operations were ultimately completed with open technique were analyzed with the open cohort, whereas patients whose operations were completed in entirety using any laparoscopic approach were analyzed with the MIS group.

Comparing oncologic outcomes in patients undergoing surgery for oncocytic neoplasms, conventional oncocytoma, and chromophobe renal cell carcinoma.

Introduction: Oncocytic neoplasms are renal tumors similar to oncocytoma, but their morphologic variations preclude definitive diagnosis. This somewhat confusing diagnosis can create treatment and surveillance challenges for the treating urologist. We hypothesize that these subtle morphologic variations do not drastically affect the malignant potential of these tumors, and we sought to demonstrate this by comparing clinical outcomes of oncocytic neoplasms to those of classic oncocytoma and chromophobe.

Assessing Cost of Robotic Utilization in Partial Nephrectomy with Increasing Utilization.

Purpose: To evaluate trends in utilization of robotic assistance in partial nephrectomy (PN) and assess the association between cost and utilization.

Patients And Methods: Using the 2009-2012 Nationwide Inpatient Sample database, we identified all adult (>17 years) patients undergoing PN for localized primary renal malignancy. Coding for robotic assistance (17.

Anatomic comparison of traditional and enucleation partial nephrectomy specimens.

Objective: To compare pseudocapsule (PC) properties of clear cell renal cell carcinoma tumors removed via both traditional partial nephrectomy (PNx) and enucleative techniques as well as quantify the difference in volume of normal renal parenchyma removed between groups.

Materials And Methods: A retrospective review of clear cell PNx specimens between 2011 and 2014 was performed. All patients undergoing tumor enucleation (TE) were included.

Treatment and Clinical Outcomes of Patients with Teratoma with Somatic-Type Malignant Transformation: An International Collaboration.

Purpose: We assessed prognostic factors, treatments and outcomes in patients with teratoma with malignant transformation, a rare occurrence among germ cell tumors.

Materials And Methods: Data on patients diagnosed with teratoma with malignant transformation between June 1981 and August 2014 were collected across 5 referral centers. Chemotherapy was dichotomized as based on germ cell tumor or teratoma with malignant transformation.

Long-term outcomes of catheterizable continent urinary channels: What do you use, where you put it, and does it matter?

Introduction: Appendicovesicostomy (APV) and Monti ileovesicostomy (Monti) are commonly used catheterizable channels with similar outcomes on short-term follow-up. Their relative long-term results have not been previously published.

Objective: Our goal was to assess long-term durability of APV and Monti channels in a large patient cohort.

Differentiating reconstructive techniques in partial nephrectomy: a propensity score analysis.

Introduction: To assess whether volumetric measurements can differentiate functional changes between reconstructive techniques after partial nephrectomy.

Materials And Methods: One hundred and fifty-six patients undergoing partial nephrectomy for a single renal mass were retrospectively studied between 2008 and 2012. Computed tomography scans were available for volume calculations on 56 (18 non-renorrhaphy and 38 renorrhaphy).

Functional and Clinicopathologic Outcomes Using a Modified Vescica Ileale Padovana Technique.

Objective: To evaluate the clinicopathologic and functional outcomes of a modified Vescica ileale Padovana (VIP) neobladder technique.

Methods: Data for 160 patients at a single institution who underwent radical cystectomy and orthotopic VIP neobladder creation between 1998 and 2013 were analyzed. Modified VIP technique involved longitudinal opening of the small bowel close to the anterior mesenteric border instead of along the true anti-mesentery.

National Trends in the Performance of Robot-Assisted Sacral Colpopexy.

Purpose: Robot-assisted sacral colpopexy (RASC) utilization trends and influencing factors were examined. RASCs were compared with nonrobotic vaginal suspension procedures (non-RASC) used to treat patients with vaginal prolapse. Hospital costs associated with each approach were also examined.

Robot-Assisted Radical Prostatectomy in Patients with a History of Holmium Laser Enucleation of the Prostate: Feasibility and Evaluation of Initial Outcomes.

Purpose: To evaluate outcomes of post-holmium laser enucleation of the prostate (HoLEP) robot-assisted radical prostatectomy (RARP).

Patients And Methods: Using an institutional database, we identified 11 HoLEP patients who subsequently underwent RARP. These were matched 1:2 to RARP patients without a previous transurethral surgical procedure.

The impact of hospital volume on postoperative complications following robot-assisted partial nephrectomy.

Purpose: We sought to evaluate the relationship between hospital volume and postoperative complications following robot-assisted partial nephrectomy (RAPN) using the Nationwide Inpatient Sample.

Materials And Methods: We identified patients undergoing RAPN between 2009 and 2011. Hospitals were divided into volume-based tertiles for each year (high, medium, low).

National trends in the utilization of robotic-assisted radical cystectomy: an analysis using the Nationwide Inpatient Sample.

Objectives: To determine temporal and regional trends in utilization of robotic-assisted radical cystectomy (RARC) in the United States and to explore factors associated with utilization of robotic assistance.

Materials And Methods: Using 2009 to 2011 data from the Nationwide Inpatient Sample, we identified radical cystectomy cases that were performed using either open or robotic assistance and applied Nationwide Inpatient Sample discharge weights to determine national incidence. Univariable and multivariable logistic regressions were performed to assess regional trends and characteristics associated with having RARC.

Short-term morbidity and mortality of Indiana pouch, ileal conduit, and neobladder urinary diversion following radical cystectomy.

Purpose: Literature surrounding Indiana pouch (IP) urinary diversion suggests a higher incidence of complications and longer operative time compared with ileal conduit (IC) and neobladder (NB). We sought to assess short-term complications of IP diversions compared with other diversions at our institution.

Materials And Methods: Using institutional National Surgical Quality Improvement Program data, we identified radical cystectomy cases performed for bladder cancer at Indiana University from January 2011 until June 2013.

Examining the relationship between operative time and hospitalization time in minimally invasive and open urologic procedures.

Objective: To explore the relationship between operative time, approach, and length of stay (LOS) in partial nephrectomy (PN), radical prostatectomy (RP), and adrenalectomy (AD).

Materials And Methods: Using the National Surgical Quality Improvement Program database, we identified all PN, RP, and AD from 2010 to 2012. Non-prostate cancer RP were excluded.
