percutaneous cystolithotomy in the pediatric neuropathic bladder with laparoscopic trocar access a modified approach useful for the augmented and native bladder and continent urinary reservoir
Journal of Pediatric Urology, 2013Co-Authors: Audrey C Rhee, Mark P CainAbstract:Abstract Objective We present our results of percutaneous cystolithotomy with laparoscopic trocar (PCLT) access in children. Materials and methods PCLT was performed in 13 cases. This includes 2 patients who had this performed twice for recurrent stone 12–24 months after initial surgery. Eight patients had a bladder augmentation, 2 had native bladders, and one a continent urinary reservoir. Nine patients had a reconstructed urethra. Cystoscopy was performed in all cases to assess stone burden. Under direct vision, an 18 gauge angiocatheter was placed into bladder and guidewire placed through the angiocatheter. With the bladder distended, a laparoscopic 10 mm trocar was placed under vision next to the guidewire. A 26Fr nephroscope was used via the trocar to extract the stones, utilizing laser or Ultrasonic Lithotripsy to fragment larger stones. Stone fragments were removed with graspers and/or the vacuum extraction technique. Results PCLT was successful in all cases. No complications were noted. Six cases were treated as outpatient, seven discharged home after 12–23 h observation. Conclusions PCLT via laparoscopic trocar access is a facile and safe approach for removing stones in the pediatric neuropathic bladder. Advantages include the ability to distend the bladder with continuous flow and the larger working channel permitting use of the nephroscope to treat and extract stones.

The Journal of Urology, 2011Co-Authors: Audrey Rhee, Mark P CainAbstract:Objective: We present our results of percutaneous cystolithotomy with laparo- scopic trocar (PCLT) access in children. Materials and methods: PCLT was performed in 13 cases. This includes 2 patients who had this performed twice for recurrent stone 12e24 months after initial surgery.

unenhanced computerized axial tomography to detect retained calculi after percutaneous Ultrasonic Lithotripsy
The Journal of Urology, 1999Co-Authors: Todd Waldmann, David B Lashley, Eugene F FuchsAbstract:AbstractPurpose: We report our experience with unenhanced computerized axial tomography (CT) after percutaneous Ultrasonic Lithotripsy in patients thought to be at high risk for retained calculi.Materials and Methods: CT was obtained in 121 patients (124 kidneys) within 12 to 36 hours of percutaneous Ultrasonic Lithotripsy for staghorn or large nonstaghorn renal calculi. Cases were grouped according to the CT findings as no retained calculi, insignificant retained calculi (fragments 1 to 3 mm.), retained calculi amenable to shock wave Lithotripsy and retained fragments requiring second look percutaneous Ultrasonic Lithotripsy or flexible nephroscopy.Results: No calculi were seen in 73 kidneys (59%) and retained calculi were identified in 51 (41%). Shock wave Lithotripsy was used to treat 8 patients and another percutaneous Ultrasonic Lithotripsy or flexible nephroscopy was performed in 23 to remove retained stones. Insignificant calculi were noted in the remaining 21 patients.Conclusions: We believe that ...

Journal of Modern Urology, 2015Co-Authors: W U XionghuAbstract:Objective To evaluate the clinical efficacy of treating staghorn calculi under percutaneous nephrolithotomy(PCNL)combined with Ultrasonic and pneumatic Lithotripsy guided by B ultrasonography.Methods A total of 150 patients with staghorn calculi were treated with PCNL combined with EMS guided by ultrasound.Results Overall,the average operation time was 83 min,perioperative bleeding volume was 142 mL,average postoperative hospital stay was 6.1 days and clearance rate of stone was 92%.The average operation time,bleeding volume,hospitalization time,and stone clearance rate of partial staghorn calculi and complete staghorn calculi was 72,117 min,128,183 mL,5.9,6.7 days,and 94.7%,83.8%,respectively.No severe complication was observed after operation.Conclusion PCNL combined with pneumatic and Ultrasonic Lithotripsy is safe and effective for renal calculus and it is the preferred method for the treatment of staghorn calculi.
