Retrograde intrarenal surgery for lower pole stones utilizing stone displacement technique yields excellent results.

Objective: To evaluate the long-term stone-free rate (SFR) of retrograde intra-renal surgery (RIRS) in the treatment of lower pole renal calculi using only basket relocation and identify independent predictors of stone-free status.

Methods: All consecutive patients undergoing RIRS lower pole renal calculi at a single high-volume tertiary center were analyzed retrospectively. Lower pole stones were relocated to the upper pole, where laser lithotripsy was performed.

Post-operative pain following percutaneous nephrolithotripsy- clinical correlates.

Objectives: Management of postoperative pain following percutaneous nephrolithotripsy (PCNL) is a significant goal. We sought to identify risk factors and clinical correlates of postoperative pain in order to improve perioperative management and patient satisfaction.

Materials And Methods: A single-center, retrospective analysis, from a prospectively maintained database, of all consecutive patients who underwent PCNL for renal calculi between January 2011 and August 2018.

Endoscopic Management of Low-Grade Upper Tract Urothelial Carcinoma: Characterizing the Long-term Burden of Care in Comparison to Radical Nephroureterectomy.

Objective: To compare procedure burden, oncologic, surgical and renal-function outcomes between patients with low-grade upper urothelial cancer (UTUC) who were referred for either radical management (RM) or kidney-sparing endoscopic management (EM).

Patients And Methods: We retrospectively reviewed data of all patients treated for UTUC at our tertiary medical center between 2000 and 2018 and selected patients diagnosed with unilateral low-grade UTUC.

Results: Twenty-four patients were treated with EM and 37 with RM.

Uroflowmetry Before and After Meatotomy in Boys with Symptomatic Meatal Stenosis Following Neonatal Circumcision - A Long-term Prospective Study.

Objective: To assess uroflowmetry in the long-term follow-up of symptomatic meatal stenosis patients prior to and following meatotomy. Severity of symptoms and treatment success has been defined by patient history, physical examination, and witnessed voiding. Uroflowmetry might add objective parameters for the assessment, however long-term data are lacking.

Comparison of Robotic Pyeloplasty and Standard Laparoscopic Pyeloplasty in Infants: A Bi-Institutional Study.

Purpose: To compare outcomes between robotic pyeloplasty (RP) and standard laparoscopic pyeloplasty (LP) in the infant population for the treatment of ureteropelvic junction (UPJ) obstruction.

Materials And Methods: We performed a retrospective cohort study of all children under 1 year of age who underwent RP or LP at two different medical centers between October 2009 and February 2016. Patient demographics, perioperative data, complications, and results were reviewed.

Minimally Invasive Approach for Treatment of Seminal Vesicle Cyst Associated with Ipsilateral Renal Agenesis.

Objectives: We reviewed the clinical presentation and approach for the treatment of symptomatic seminal vesicle cyst associated with ipsilateral renal agenesis while presenting our experience with a series of 5 patients treated with minimally invasive surgery for Zinner syndrome.

Materials And Methods: Between the years 2008 and 2016, we operated on 5 patients who presented with symptomatic seminal vesicle cyst and ipsilateral renal agenesis. Patients' charts and medical records were reviewed and compared with past published minimally invasive series.
