The Effect of Pre-Stenting on Bleeding-Related Complications Following Ureteroscopy in Patients on Anticoagulation or Antiplatelet Therapy.

The American Urological Association guidelines state that continuing anticoagulant (AC) and antiplatelet (AP) agents during ureteroscopy (URS) is safe. Through a multi-institutional retrospective study, we sought to determine whether pre-stenting in patients on AP or AC was associated with fewer URS bleeding-related complications. A series of 8614 URS procedures performed across three institutions (April 2010 to September 2017) was electronically reviewed for AC/AP use at time of URS.

Antibiotics are not necessary during routine cystoscopic stent removal: A randomized controlled trial at UC San Diego.

Introduction: Current American Urological Association (AUA) Best Practice Statement recommends antibiotic prophylaxis for cystoscopy with manipulation, including stent removal; although no Level 1b trials explicitly address prophylaxis for stent removal. We sought to determine the efficacy of prophylactic antibiotics to prevent infectious complications after stent removal.

Materials And Methods: Following institutional review board approval, patients undergoing removal of ureteral stent placed during stone surgery were recruited from July 2016 to March 2019.

Nephrostomy tubes placed emergently prior to percutaneous renal stone surgery are practical for obtaining access.

Objectives: Renal access in percutaneous nephrolithotomy (PCNL) may be obtained via a pre-existing nephrostomy tube (NT) tract; however, emergent NTs are not always ideal for subsequent surgery. We sought to determine the rate of NT tract usability and assess factors related to the usability of emergently placed NTs.

Methods: A retrospective review was performed of UC San Diego subjects undergoing percutaneous renal surgery between January 2016 and October 2018.

Minimally Invasive Percutaneous Nephrolithotomy: Initial North American Experience.

The goal of this study is to evaluate the outcomes in a cohort of patients who underwent minimally invasive percutaneous nephrolithotomy (MIP) at a single institution from 2017 to 2019. Sixty patients at a single institution with two different surgeons underwent MIP from 2017 to 2019. The MIP technique uses a proprietary nephroscope with a "vacuum" technique for stone evacuation.

Use of the Quick Sequential Organ Failure Assessment Score for Prediction of Intensive Care Unit Admission Due to Septic Shock after Percutaneous Nephrolithotomy: A Multicenter Study.

Purpose: Recent studies have demonstrated that quick sequential organ failure assessment criteria may be more accurate than systemic inflammatory response syndrome criteria to predict postoperative sepsis. In this study we evaluated the ability of these 2 criteria to predict septic shock after percutaneous nephrolithotomy.

Materials And Methods: We performed a retrospective multicenter study in 320 patients who underwent percutaneous nephrolithotomy at a total of 8 institutions.

Outpatient Percutaneous Nephrolithotomy: The UC San Diego Health Experience.

Introduction: Outpatient percutaneous nephrolithotomy (PCNL) has been described for highly selected patients. We sought to assess the safety and feasibility of outpatient PCNL in a tertiary referral stone center without strict patient selection criteria.

Materials And Methods: We reviewed all PCNLs performed at our institution from September 2015 to October 2016.
