    COMPLETE SUPINE PERCUTANEOUS NEPHROLITHOTOMY - OUTCOMES OF A PROSPECTIVE SERIES OF A SINGLE SURGEON
    (2012) VICENTINI, Fabio Carvalho; HISANO, Marcelo; MAZZUCCHI, Eduardo; CLARO, Joaquim Almeida; MURTA, Claudio Bovolenta; SROUGI, Miguel
    OBJECTIVE: To describe our technique and results. METHODS: A total of 117 patients (120 renal units) were evaluated in a prospective manner. One surgeon operated all the cases. All patients had a CT scan pre-operatively and the stones were classified according the Guy’s score. We performed complete supine PCNL (csPCNL) with no rolled towel under the flank and no change of position. The ipsilateral arm was hung over the thorax and the patients were draped only once. A 6Fr ureteral catheter was placed without lithotomy position. The puncture was done always by the surgeon in the selected calix under fluoroscopic vision. The tract was dilated with a double shot technique and a 30Fr Amplatz sheath was placed. A 16Fr nephrostomy tube was inserted in cases of bleeding or residual stones. A ureteral catheter or a double J was always left. A CT scan was done in the first POD in all cases. Success was defined as the presence of ≤ 4 mm fragments at the end of follow up. RESULTS: The operative time ranged between 20 and 240 minutes (mean 105.5±50.8 min). The immediate success rate was 72.5% and the final rate was 90.4% after an average of 1.08 PCNL and 0.17 auxiliary procedures. Patients were left tubeless in 38.3% of the cases. The complication rate was 15.8% (11.6% of Clavien 1 or 2 and 4.2% of Clavien 3 or 4). The transfusion rate was 4.2%. No colon injuries or deaths occurred. CONCLUSIONS: The csPCNL is a very safe and effective procedure.

    THE GUY'S STONE SCORE: A VERY PRACTICAL AND USEFUL TOOL TO PREDICT THE OUTCOMES OF PERCUTANEOUS NEPHROLITHOTOMY (PCNL)
    (2012) VICENTINI, Fabio Carvalho; MARCHINI, Giovanni Scala; MAZZUCCHI, Eduardo; CHEDID NETO, Elias Assad; BRITO, Arthur Henrique; DANILOVIC, Alexandre; HISANO, Marcelo; CLARO, Joaquim Almeida; SROUGI, Miguel
    OBJECTIVE: To evaluate the applicability of the Guy’s stone score for complete supine PCNL. METHODS: 117 patients that underwent to complete supine PCNL were classified according the Guy’s stone score. The data were prospectively collected but the classification according to the score was done by review of the pre-operative CT scans. All patients were operated by the same surgeon and had a pre and post operative CT scan and at the final followup. The outcomes and complications were compared among the 4 groups. RESULTS: The table 1 shows the demographic and outcomes. The groups were similar except for the median stone diameter. The differences among groups were statistically different after stratification according to the Guy’s stone score in relation to operative time, hemoglobin drop, transfusions, complications, tubeless rate, immediate success, auxiliary procedures, PCNL revisions and final success rate. CONCLUSIONS: The Guy’s stone score showed to be a very practical and useful tool to predict the outcomes of PCNL.

    Use of the Uro Dyna-CT in endourology - the new frontier
    (2017) VICENTINI, Fabio C.; BOTELHO, Luiz A. A.; BRAZ, Jose L. M.; ALMEIDA, Ernane de S.; HISANO, Marcelo
    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. Prospective studies will define the real role of the Uro Dyna-CT for endourological procedures, but its use seems to be a very promising tool for improving stone free rates and decreasing auxiliary procedures, especially for complex cases.

    Retroperitoneoscopic adrenalectomy in pheochromocytoma
    (2012) HISANO, Marcelo; VICENTINI, Fabio Carvalho; SROUGI, Miguel
    Since the first laparoscopic adrenalectomy, the technique has evolved and it has become the standard of care for many adrenal diseases, including pheochromocytoma. Two laparoscopic accesses to the adrenal have been developed: transperitoneal and retroperitoneal. Retroperitoneoscopic adrenalectomy may be recommended for the treatment of pheochromocytoma with the same peri-operative outcomes of the transperitoneal approach because it allows direct access to the adrenal glands without increasing the operative risks. Although technically more demanding than the transperitoneal approach, retroperitoneoscopy can shorten the mean operative time, which is critical for cases with pheochromocytoma where minimizing the potential for intra-operative hemodynamic changes is essential. Blood loss and the convalescence time can be also shortened by this approach. There is no absolute indication for either the transperitoneal or retroperitoneal approach; however, the latter procedure may be the best option for patients who have undergone previous abdominal surgery and obese patients. Also, retroperitoneoscopic adrenalectomy is a good alternative for treating cases with inherited pheochromocytomas, such as multiple endocrine neoplasia type 2A, in which the pheochromocytoma is highly prevalent and frequently occurs bilaterally.
