PURPOSE: Topical therapy (TT) for upper tract urothelial carcinoma (UTUC) has been explored as a kidney sparing approach to treat carcinoma in situ (CIS) and as adjuvant for endoscopically treated Ta/T1 tumors. In bladder cancer, data support use of salvage TT for repeat induction. We investigate the outcomes of salvage TT for UTUC in patients ineligible for or refusing nephroureterectomy. METHODS: A single-center retrospective review on patients receiving salvage TT via percutaneous nephrostomy tube or cystoscopically placed ureteral catheters was performed...

BACKGROUND: Predictive tables and scoring systems can predict stone clearance. However, there is a paucity of evidence regarding the prediction of complications during percutaneous nephrolithotomy (PCNL), particularly in children, which remains under-researched. To our knowledge, no studies have evaluated the risk factors for febrile urinary tract infection (FUTI) after pediatric PCNL. OBJECTIVES: To assess the predictive factors of FUTI in prepubertal children after PCNL and determine whether any prophylactic cephalosporins are superior for decreasing the FUTI rate...

Biomaterials for applications in the urinary tract are challenged with both biofilm formation and encrustation, two highly interconnected processes. While great effort has been achieved developing promising materials there is only a limited choice of sophisticated in vitro models that are available to analyse the performance of biomaterials prior to performing delicate and expensive in vivo studies. In this study we present a complex BioEncrustation model that imitates both the processes of multi-species biofilm formation and encrustation in vitro...

BACKGROUND: Leiomyomas can develop after hysterectomy and, when located in the bladder, can result in voiding dysfunction and incontinence. CASE: Fifty years after a hysterectomy, a 77-year-old woman presented with a 1-year history of urinary retention requiring self-catheterization and bothersome urinary incontinence. Multiple imaging modalities demonstrated a well-circumscribed 2-cm mass abutting the bladder beneath the trigone. After ureteral stent placement, we excised the nonpalpable mass using ultrasound guidance...

Iatrogenic urinary tract injuries are known complications of digestive and pelvic surgeries. We retrospectively reviewed 13 patients with bladder injuries and 16 patients with ureteral injuries requiring surgical repair or stent placement in our hospital between 2013 and 2016. Obstetric-gynecologic surgery accounted for 10 bladder injuries and 11 ureteral injuries on hysterectomy and Cesarean section. Digestive surgery led to 1 bladder injury and 5 ureteral injuries on colon resection, and urologic surgery resulted in 1 injury on biopsy of a retroperitoneal tumor...

Background: Urinary tract stones is one of the most frequent medical emergencies which leads to life-threatening complications, namely obstructive uropathy as well as renal failure in some situations. Previously, bilateral stones were treated with either open surgery or percutaneous nephrolithotomy (PCNL). However, these treatment options were associated with lengthy operation time, need for more anesthesia, further bleeding, and long hospitalization. Therefore, much effort has been made to treat both sides simultaneously...

Objective: Cryoablation of renal tumors adjacent to the ureter or pelvicalyceal system carries risks for thermal injury of the collecting system. Although cold antegrade perfusion has been described for radiofrequency ablation, warm saline perfusion for renal cryoablation has not been well-characterized. The purpose of this study was to determine the safety and feasibility of antegrade and retrograde warm saline perfusions during percutaneous renal cryoablation. Material and methods: A retrospective review was performed on 136 patients treated with percutaneous renal cryoablation at a single academic institution between 2009 and 2015...
