There is a very low rate of early prostate cancer detection in Latin America, since patients usually are diagnosed when the disease is in advanced stages. Sporadic prostate cancer screening campaigns do exist which allow us to diagnose this disease in earlier stages. Incidence and mortality rates differ widely from country to country, and they are probable underreported in our region since registers may be city-based instead of country-based.

Introduction: Acquired urachal anomalies are a rare pathology. Gold-standard treatment for this clinical situation remains the resection of the urachus in its entire tract with or without partial resection of the bladder. Our aim is to up-date authors's experience in the minimally invasive surgical treatment of acquired urachal disease., Methods: From 2001 to 2007, 14 patients were operated for acquired urachal disease at our institution. A three portal technique previously described by the authors was employed. The diagnosis of acquired uracal disease was confirmed in all cases and the resection of the urachus in its entire tract performed in cephalocaudal direction onto the bladder. Operative and demographic data was prospectively collected and analysis retrospectively performed., Results: Mean operative time was 63 minutes (45,110), minimal blood loss, and no conversions to open surgery or perioperative complications were verified. The majority of the patients were discharged in the first 24 hours. At a follow-up of 22 months no recurrences of urachal pathology recurrences have been verified., Conclusions: Laparoscopy plays a significant role in the management of symptomatic urachus anomalies. It allows objective confirmation of clinical diagnosis and adequate resection of the urachus in a safe and efficient fashion, while providing the well-known advantages of minimally acces surgery. Preoperative evaluation work-up has minimal impact of therapeutical decision.

Objective: We present our initial experience in laparo-endoscopic single site (LESS) surgery, through multichannel port, articulated instruments and standard instruments adapted others adapted for the procedures., Materials and Methods: Between February and October 2008, 28 LESS surgical procedures with multi-port were performed (Transumbilical simple prostatectomy (PSTU) and transvesical (PSTV), simple nephrectomy (NS), Enterocystoplasty augmentation (ECA) and simple hysterectomy (HS)). The clinical data were collected prospectively and analyzed retrospectively. Was used access device Multichannel (R-Port). The procedures were performed for a single surgeon (RS). The surgical technique was the same route used by conventional laparoscopic., Results: Twenty-eight surgeries were performed: PSTU (01), PSTV (20), NS (01), ECA (01), HS (05). The incision was performed umbilical or infraumbilical. Only one case (nephrectomy) needed it placement of an additional trocar. The average age by procedure was PSTU and PSTV, 67- and 68-year-old (57-89 y) respectively; NS 12 year-old; RCT 20-year-old; HS 46.4-year-old (41 - 54 y). The operative time was: PSTU 120 minutes, PSTV 91 minutes (45-210 min); NS 120 minutes: RCT 300 minutes; HS 112 minutes(90-160 min). The operative bleeding was PSTU and PSTV 200 cc. and 337 cc (50-1500 cc) respectively; NS 100 cc; EAC 100 cc; HS 118 cc (100-160 cc). The complication was haematury in two cases of PSTV, both patients required exploration postoperative endoscopic with satisfactory evolution., Conclusions: LESS is a feasible and reproducible surgical option in uro-gynecologic surgical treatment. Further studies, experience and follow-up will provide an objective assessment of the technique.
