Laparoscopic and robotic surgery for stone disease.

Urolithiasis 2018 Feb 23;46(1):125-127. Epub 2017 Nov 23.

Sobeh's Vascular and Medical Centre, Dubai Health Care City, Dubai, UAE.

Treatment for stone disease has evolved drastically during the past 3-4 decades. Ureteroscopy, percutaneous nephrolithotomy along with SWL, provides the means to treat practically all urinary tract stones with minimal invasion to the patients. However, for complex stone case scenarios where open surgery is being considered, a less invasive and better tolerated option such as laparoscopy (robot assisted or not) can be performed. Read More

Simulation training in upper tract endourology: myth or reality?

Minerva Urol Nefrol 2017 Dec 30;69(6):579-588. Epub 2017 Mar 30.

MRC Centre for Transplantation, King's College, London, UK -

Surgeons training in the twenty-first century are subject to a myriad of pressures, as has always been the case within surgical training. These include reduced hours available for training and increased threat of litigation against their operating practice. The Halstedian approach of "see one, do one, teach one" has been replaced within surgical training and simulation has become established to enable urology trainees to develop technical and non-technical skills away from the operating room.

Use of the Uro Dyna-CT in endourology - the new frontier.

Int Braz J Urol 2017 Jul-Aug;43(4):762-765

Departamento de Urologia, Centro do Cálculo Renal do Hospital 9 de Julho, São Paulo, Brasil.

We describe the use of the Uro Dyna-CT, an imaging system used in the operating room that produces real-time three-dimensional (3D) imaging and cross-sectional image reconstructions similar to an intraoperative computerized tomography, during a percutaneous nephrolithotomy and a contralateral flexible ureteroscopy in a complete supine position. A 65 year-old female patient had an incomplete calyceal staghorn stone in the right kidney and a 10mm in the left one. The procedure was uneventful and the intraoperative use of the Uro Dyna-CT identified 2 residual stones that were not found by digital fluoroscopy and flexible nephroscopy at the end of surgery, helping us to render the patient stone-free in one procedure, which was confirmed by a postoperative CT scan.
