- Acute segmental renal infarction due to factor V LeidenPublication . Cabral-Ribeiro, J; Sousa, L; Calaza, C; Santos, AOBJECTIVE: Renal infarction is rare and has variable clinical presentations causing diagnostic difficulties. Although most renal infarctions are caused by an obvious thromboembolic factor some are only explained by hereditary or acquired thrombophilia. The authors present a case of segmental renal infarction associated with factor V Leiden. METHODS/ RESULTS: A 48-year-old man presented with right flank pain that was unresponsive to analgesia for renal colic. CT scan was performed revealing a partial renal infarction. The etiologic study was only positive to factor V Leiden. In spite of the diagnosis and treatment it resulted in atrophy of the affected renal area. CONCLUSIONS: Renal infarction can be a presentation of thrombophilia that should be searched in the absence of an obvious embolic factor. Renal CT scan is the best way to a rapid diagnosis and treatment.

- Collecting system percutaneous access using real-time tracking sensors: first pig model in vivo experiencePublication . Rodrigues, PL; Vilaça, JL; Oliveira, C; Cicione, A; Rassweiler, J; Fonseca, J; Rodrigues, NF; Correia-Pinto, J; Lima, EPURPOSE: Precise needle puncture of the renal collecting system is a challenging and essential step for successful percutaneous nephrolithotomy (PCNL). This works aims to evaluate the efficiency of a new real-time electromagnetic tracking (EMT) system for in vivo kidney puncture. MATERIALS AND METHODS: Six anesthetized female pigs underwent ureterorenoscopies in order to place a catheter with an EMT sensor into the desired puncture site and to ascertain the success of puncture. Subsequently, a tracked needle with a similar EMT sensor was navigated into the sensor inside the catheter. Four punctures were performed by two surgeons in each pig: one in the kidney and one in the middle ureter, on both right and left pig sides. Number of attempts and time needed to evaluate the virtual trajectory and to perform the percutaneous puncture were outcomes measurements. RESULTS: Overall 24 punctures were easily performed without any complications. Surgeons required more time to evaluate the trajectory during ureteral puncture than kidney (median 15 versus 13 seconds, range 14 to 18 and 11 to 16 seconds, respectively; p= 0.1). The median renal and ureteral puncture time were 19 and 51 seconds respectively (range 14 to 45 and 45 to 67; p=0.003). Two attempts were needed to achieve a successful ureteral puncture. The presented technique demands presence of renal stone for testing. CONCLUSIONS: The proposed EMT solution for renal collecting system puncture proved to be highly accurate, simple and quicker. This method might represent a paradigm shift in percutaneous kidney access techniques.
- Consensus statement on natural orifice transluminal endoscopic surgery and single-incision laparoscopic surgery: heralding a new era in urology?Publication . Gettman, MT; Box, G; Averch, T; Cadeddu, JA; Cherullo, E; Clayman, RV; Desai, M; Frank, I; Gill, I; Gupta, M; Georges-Pascal, H; Humphreys, M; Kaouk, J; Landman, J; Lima, E; Ponsky, L
- Current status and future perspectives in laparoendoscopic single-site and natural orifice transluminal endoscopic urological surgery.Publication . Autorino, R; Stein, RJ; Lima, E; Damiano, R; Khanna, R; Haber, GP; White, MA; Kaouk, JHObjective of this study is to provide an evidence-based analysis of the current status and future perspectives of scarless urological surgery. A PubMed search has been performed for all relevant urological literature regarding natural orifice transluminal endoscopic surgery (NOTES) and laparoendoscopic single-site surgery (LESS). In addition, experience with LESS and NOTES at our own institution has been considered. All clinical and investigative reports for LESS and NOTES procedures in the urological literature have been considered. A wide variety of clinical procedures in urology have been successfully completed by using LESS techniques. Thus far, experience with NOTES has largely been investigational, although early clinical reports are emerging. Further development of instrumentation and platforms is necessary for both techniques to become more widely adopted throughout the urological community.
- Early experience in laparoscopic radical prostatectomy using the laparoscopic device for umbilical access SILS PortPublication . Bachiller Burgos, J; Alonso Flores, J; Sánchez De La Vega, J; Beltrán Aguilar, V; Salazar Otero, S; Brás Silva, CSince 2007, various urological procedures have been performed with laparoendoscopic single-site surgery (LESS surgery), including nephrectomy, pyeloplasty, simple prostatectomy and, with the refinement of laparoscopic instrumentation, radical prostatectomy. This paper reports our initial experience in radical prostatectomy using the SILS Port from Covidiem and two lateral 5-mm trocars for triangulation. The SILS Port allows for accurate, simple insertion through a Hadson incision. The flexible port accommodates three 5-mm cannulas or two 5-mm cannulas and a 12-mm port for easier instrument exchange through a single incision. This approach decreases morbidity from bleeding, hernia and/or internal organ damage and improves cosmetic. One-port single-incision laparoscopy is part of the natural development of minimally invasive surgery. Future research is required to assess the intraoperative and postoperative benefits of LESS surgery as compared to standard laparoscopy.
- Endometrioma suburetralPublication . Cabral-Ribeiro, J; Pérez García, D; Martins-Silva, C; Ribeiro-Santos, AEndometriosis is a common disease affecting mostly women in childbearing age. It usually involves the internal pelvic organs but occasionally can present in unusual locations. We report on a 32-year-old nulliparos female presenting with a suburethral painful mass causing obstructive voiding symptoms; she had also a long history of dismenorreia, perimenstrual pelvic pain, urinary tract infections, disúria and dispareunia. The diagnostic work-up revealed a suburethral cystic lesion consistent with a complicated urethral diverticulum or a suburethral endometrioma. Complete surgical excision confirmed an endometriotic cyst. The differential diagnosis of this rare suburethral location of endometriosis with other vaginal cysts is discussed.
