Nefroureterectomía laparoscópica: nueva posición para el manejo ureteral
Aguilera Bazán,Alfredo; Alonso y Gregorio,Sergio; Pérez Utrilla,Manuel; Cansino Alcaide,Ramón; Cisneros Ledo,Jesús; Pe?a,Javier de la;
Archivos Espa?oles de Urología (Ed. impresa) , 2007, DOI: 10.4321/S0004-06142007000600009
Abstract: objectives: the main challenge of laparoscopic nephroureterectomy is the management of distal ureter, which also will have an important repercussion in the oncological outcome of many cases. we present our experience in such aspect, considering that we performed the last five laparoscopic nephroureterectomies in forced trendelemburg position, resulting in a more comfortable and safe management of the distal ureter. methods: between august and december 2006 we performed five purely laparoscopic nephroureterectomies with bladder cuff positioning the patient in forced trendelemburg, a position similar to that of laparoscopic radical cystectomy or prostatectomy. results: mean surgical time was 182 minutes (170-210). mean blood loss was 100 cc and no patient required transfusion. mean hospital stay was four days. conclusions: we believe this position is a good alternative for the management of the distal ureter during the laparoscopic approach. the technique is very similar to open surgery, which continues being the gold standard today.

Archivos Espa?oles de Urología (Ed. impresa) , 2006, DOI: 10.4321/S0004-06142006000900008
Abstract: objetive: the prevalence of the disease is 1/3000 newborns; it is more frequent in men than in women with a 3:1 ratio in all races. genitourinary tract neurofibromas usually arise from the pelvic and bladder nerves, and the prostatic plexus. bladder is the most frequently affected organ of the urinary tract; bladder neurofibromatosis may present as a diffuse infiltrative process or an isolated neurofibroma. bladder neurofibromas arise from nervous ganglia of the bladder wall and stain positive for protein s-100 and type iv collagen with immunohistochemical techniques. methods: we performed a bibliographic review about urinary tract neurofibromas, and specifically of bladder neurofibroma. we report the case of a 45-year-old female consulting for voiding symptoms and recurrent urinary tract infections. imaging tests showed a mass in the left lateral wall of the bladder and diffuse thickening of the bladder wall. the thickening of the bladder wall is the most characteristic finding in imaging tests, which may also be present in other diseases such as inflammatory pseudotumor and leiomyoma, so that final diagnosis should be achieved by pathologic study. results: the case is relevant for the absence of previous diagnosis of neurofibromatosis, being bladder involvement its clinical debut. this is why it was difficult to suspect the final diagnosis: the absence of other characteristic clinical manifestations of the disease. transurethral resection of the tumor was performed and pathologic and immunohistochemical studies offered the final diagnosis. the patient was followed in the urology clinic and also sent to the internal medicine department to rule out other organs involvement of the disease. conclusions: neurofibromatosis is a rare systemic disease, and urinary tract involvement is rarer. bladder is the most frequently involved organ in the urinary tract, generally as a diffuse infiltration or more rarely a solitary tumor. the final diagnosis is pathological and immuno

Abstract: objectives: to review the outcomes of the ureteroenteric strictures treated by endourological techniques in our department, and to compare our long-term results with other reported series with similar follow-up and number of patients. methods: we retrospectively reviewed 27 ureteroenteric strictures treated from march 1994 to june 2003, with a mean follow-up of 30.2 months (1 day-53 months). 13 cases underwent ballon dilation + permanent double j catheter(3 of them antegrade) 8 patients underwent endoscopical incision + double j catheter (5 of them with acucise? results: 12/21(57,14%) renal units improved and/or remained stable. we emphasize the absence of peroperative complications except 1 case that had a very poor oncological prognosis and died of septicemia 1 day after balloon dilation. conclusions: endourological treatment of ureteroenteric strictures has demonstrated to provide good fuctional results on the short and midterm in patients that open surgery, although being the treatment of choice, would be too aggressive due to their disease, age, morbid conditions,…

Creating Scenarios and Guiding Learning in a Medical Simulation Center  [PDF]
Gregorio Ma?eru Zunzarren, Alfredo Rodriguez-Sedano
Creative Education (CE) , 2011, DOI: 10.4236/ce.2011.23044
Abstract: In this article we propose to address the importance of learning scenarios in a simulation center in graduate studies in Medicine. We will describe in detail the context in which this learning is developed. To do this, we need to reflect briefly on the contents that permit the configuration of these scenarios as teaching units, the objectives which should be commensurate with the level of training and experience of the students, the activities to develop and the means by which these are arranged, and, finally, the evaluation of the process. The development of this learning would not be possible without an activity guide, as a well as an evolution and debriefing stage.
Reparación laparoscópica de la fístula vesicovaginal (O'Connor laparoscópico)
Alonso y Gregorio,Sergio; álvarez Maestro,Mario; Cabrera Castillo,Pedro M.; Hidalgo Togores,Luis; Pe?a Barthel,J. Javier de la;
Actas Urológicas Espa?olas , 2009, DOI: 10.4321/S0210-48062009001000017
Abstract: introduction: the most frequent cause of vesicovaginal fistula in developed countries is hysterectomy, while in the third world it is related to time in labour. any surgical iatrogenic trauma implies encountering added difficulties of various kinds when repairing the condition. material and method: we report the first case of vesicovaginal fistula to be resolved laparoscopically in our department. the patient is a woman 50 years of age who had undergone an abdominal hysterectomy 8 months previously, and who presented a syndrome compatible with vesicovaginal fistula. she was referred to our division after an unsuccessful attempt at vaginal repair. we will now describe the laparoscopic vesicovaginal fistula repair procedure. results: the surgical procedure lasted approximately 3 hours and 30 minutes. the patient began oral intake 48 hours after surgery, normal intestinal transit was restored by the 5th day, a cystography was performed on the 7th day, and the patient was discharged on the 8th day. the patient remains asymptomatic after more than a year and a half. conclusions: laparoscopic resolution of vesicovaginal fistula is perfectly feasible and safe. if we consistently reproduce the principles applied in the open surgery, it offers the same success rate with the lowest possible morbidity.

Abstract: introduction: nephroureterectomy is one of the procedures for which a laparoscopic approach is more clearly indicated. however, despite the long experience available, management of the distal ureter is still difficult. materials and methods: thirty-two laparoscopic nephroureterectomies were performed from november 2004 to december 2008. the procedure used was endoscopic resection of distal ureter and earlier ligation of the ureter in the laparoscopic time in 13 patients, a laparoscopic bladder cuff in 13 patients, and an open bladder cuff in 3 patients. results: mean operating time was 221.53 min (125-315 min), and mean postoperative stay of 27 patients was 4.6 days. conversion to open surgery and discontinuation of the procedure for local tumor progression were required in one patient each. mean patient follow-up was 17.8 months. no local relapse or metastasis occurred in the ports. conclusion: the most common procedures continue to be endoscopic resection and the open bladder cuff depending on indication. any laparoscopic approach to upper urothelial tumors must strictly comply with oncological principles. the reported procedure is in our experience the fastest, most simple, and most effective for this purpose. in our opinion, the therapeutic algorithm provided is adequate for management of the distal ureter in laparoscopic nephroureterectomy.
