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...

INTRODUCTION: Ureter stenosis in renal transplantation patients is a relatively frequent complication that negatively conditions graft evolution. The use of ureteral stents is a valid treatment alternative to the use of double-J catheters in patients for whom surgery is not contemplated or after surgical recurrence. We present our initial experience with five patients treated using this technique. MATERIALS AND METHODS: We describe a total of five patients with ureteral stenosis after renal transplantation who were treated using ureteral stent model UVENTA (Taewoong Medical, Seoul, Korea) in our center...

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...

Background: After almost two decades, transabdominal robotic radical prostatectomy techniques have been fully developed and are widely practiced by many robotic urologists. Recently, a transperineal robotic radical prostatectomy, a technique not yet popular to many, was introduced as an alternative approach in patients with previous abdominal surgery. Here, we present our unique experience with robotic perineal radical prostatectomy (r-PRP) on a kidney transplant recipient. Case Presentation: A 71-year-old man who had a kidney transplant 4 months previously was diagnosed with prostate cancer (PCa) and underwent r-PRP using the da Vinci Xi robotic system...

Suprapubic cystostomy is a widely employed procedure that is used to drain the bladder. Despite being a safe procedure, suprapubic cystostomy has been reported to present multiple intra- and postoperative complications. Serious and unusual complications can occur during changing of the suprapubic catheter (SPC) in patients with neuropathic bladder. In this work, we report an elderly patient with neuropathic bladder suffering from an unusual complication involving migration of the SPC into the ureter during changing of the SPC, leading to ureteric obstruction and left pyelonephritis...

Background: The experience with uretero-arterial fistulas has been limited. However, the aggressive treatment of pelvic tumors with surgical resection and radiotherapy, along with liberal use of ureteral catheters, has been attributed to an increase in their incidence. Unless they are promptly diagnosed and treated, uretero-arterial fistulas are associated with considerably high rates of morbidity and mortality. Urologists need maintain a high degree of suspicion for uretero-arterial fistula in high-risk patients...

OBJECTIVE: To describe our ultrasound technique for confirming intraoperative, antegrade-placed ureteral stent position during laparoscopic pyeloplasty. BACKGROUND: Disadvantages of retrograde stent placement include the need to reposition the patient into and out of the lithotomy position. Antegrade stent placement can reduce procedure time but requires confirming appropriate distal placement into the bladder with cystoscopy, percutaneous drain placement, or instillation of methylthioninium chloride or indigo carmine...

Introduction: The incidence of urinary leakage is increased as nephron sparing surgery becomes more used for the management of small renal masses. We present an endourologic approach in a patient with a persistent urinary leak after partial nephrectomy by placing two synchronous ureteral stents to improve drainage and avoid further potential surgery. Patients and Method: A 39-year-old patient presented with a urine leak on the fifth postoperative day after an open partial nephrectomy. Initially, the leakage was managed with a placement of a 6F Double-J stent...
