Re: Critical Analysis of Early Recurrence after Laparoscopic Radical Cystectomy in a Large Cohort by the ESUT

okThe authors critically analyze a large cohort by the European Association of Urology Section of Uro-Technology and assess early recurrences after laparoscopic radical cystectomy and evaluation of risk factors, including the impact of pneumoperitoneum. They focus their analysis on patients with favorable pathology (pT2 N0 R0 disease), \ufb01nding that 27 of 311 patients (8.7%) experienced recurrences during the following 24 months. Surgical negligence was observed in only 1 patient, which was associated with the endo bag rupturing during transvaginal extraction with subsequent vulvar and peritoneal tumor metastasis after 4 months. Among the 27 patients with recurrence a shorter recurrence-free survival was signi\ufb01cantly predictive of cancer speci\ufb01c death (HR 0.86, 95% CI 0.78e0.94, p \ubc 0.001) as well as carcinoma in situ on pathological examination (HR 3.68, 95% CI 1.07e12.7, p \ubc 0.039). While analyzing causes of early recurrence, the authors suggest that the continuous insuf\ufb02ation-desuf\ufb02ation and leakage of gas around the portsdwith consequent aspiration of tumor cells via a chimney effectdmay promote tumor seeding (TS)

Bilateral spermatic cord en bloc ligation by laparoendoscopic single-site surgery: preliminary experience compared to conventional laparoscopy

BACKGROUND: Laparo Endoscopic Single-site Surgery (LESS) represents an evolution of minimally invasive surgery and aims to improve cosmetic outcome and reduce surgical trauma and complications associated with traditional laparoscopy. This study was performed to present our preliminary experience in bilateral spermatic cord ligation with the LESS technique and compare the results with the outcomes of conventional laparoscopic surgery. METHODS: Between June 2007 and May 2013, 24 patients were referred to our institute for bilateral varicocelectomy. The indications for this type of procedure were bilateral varicocele with impairment of semen parameters or chronic bilateral testicular pain. All procedures were performed via the same surgeon. The patients were divided into two groups according to the type of laparoscopic surgery. Group A included 10 patients underwent LESS technique while group B included the remaining 14 patients that underwent conventional laparoscopy. RESULTS: The comparison between the two techniques showed some important advantages for LESS: shorter operating time (45.4 min vs. 88.3 (P\u2009<\u2009.001), shorter hospital stay (16.6 hours vs. 51.4 hours) (P\u2009<\u2009.001), early return to the normal activity (2.3 days vs. 4.7 days) and better cosmetic outcomes. No conversions from LESS to conventional laparoscopy were necessary and blood loss was insignificant in all patients.All patients in the LESS group reported full satisfaction with the cosmetic outcome, whereas 85.7% of patients after conventional laparoscopy were fully satisfied with cosmesis. CONCLUSIONS: Bilateral spermatic cord ligation with LESS is an alternative to conventional laparoscopy. The procedure was successfully performed in all patients. The trans-umbilical approach offers the advantage of a better cosmetic result, shorter hospital stay and less postoperative pain

Chronic, nonspecific, postinfectious, retroperitoneal fibrosis and ureteral obstruction

ABSTRACT Introduction: Two cases of severe ureteral obstruction following nonspecific, postinfectious, chronic retroperitoneal fibrosis are described, which both originated by a primitive intestinal pathology. Patients: This complication was observed in two women: first, 65 years old, submitted for ulcerative colitis to a total proctocolectomy, with ileo-pouch-anal anastomosis, complicated by an anastomotic fistula; and second, 66 years old, operated with an extended left hemicolectomy, for an adenocarcinoma of the recto-sigmoid colon complicated with a vaginal fistula. In these cases, computerized tomography demonstrated a unilateral hydronephrosis, secondary to a complete obstruction of the ureter; a subsequent nephro-ureterectomy became necessary. Histology demonstrated nonspecific inflammatory lesions. Discussions: Postinfectious, chronic inflammation of the retroperitoneum acts on the ureteral and peri-ureteral tissues, inducing an inflammatory and then a fibrotic process. Conclusions: We underline the opportunity of a precocious and radical treatment of every retroperitoneal infection.

Retroperitoneoscopic single site renal biopsy surgery: right indicatioBMC Urology ns for the right technique.

Bacground: Laparoendoscopic single-site surgery (LESS) has been developed in an attempt to further reduce the morbidity and scarring associated with laparoscopic surgery. In patients in whom there are indications to perform a laparoscopic renal biopsy, LESS surgery is a valid alternative to mini invasive surgery and is becoming more common. We report our experience on 14 renal biopsy procedures performed in a retroperitoneal LESS. Methods: LESS renal biopsy was performed in 14 patients 18 to 80 years old (mean age 58.3 years) during a 36 month period. All procedures were performed by a single operator. The patient was in a standard flank position. The procedure was performed using a 2.5 cm, single incision via a retroperitoneal access at the Petit ’ s triangle. A 5 mm biopsy forceps was used to collect the specimen under direct vision, and haemostasis was obtained with an Argon beam probe and the application of oxidized regenerated cellulose gauze. Results: Biopsy was performed successfully in all cases. Mean operative time was 52.64 min, blood loss was minimal, and the hospital stay ranged from 12 to 24 hours. None of the patients required narcotics or additional analgesia in the postoperative period. No postoperative complications occurred. Conclusions: The LESS technique is safe, reliable (100% success), easy to learn, and offers subjective cosmetic benefits to the patient. Minimal hospitalization requirement following retroperitoneal LESS biopsy is an additional timely advantage over laparoscopic renal biopsy. We think that with the right indications (marked obesity, failure of previous percutaneous biopsy attempts, a solitary kidney and coagulopathy) LESS renal biopsy is a good alternative to laparoscopy. Our next step will be a randomized prospective study of LESS compared with laparoscopy for renal biopsy to support our findings

Effectiveness of D-mannose, Hibiscus sabdariffa and Lactobacillus plantarum therapy in prevention of infectious events following urodynamic study

The urodynamic study is an invasive examination that allows a thorough evaluation of the functional activity of the lower urinary tract (bladder, urethra). The execution of urodynamic study exposes the patient to the risk of contracting infections of the lower urinary tract. Prevention of urinary tract infections consists in the avoidance of risk factors and prophylaxis with antimicrobial and non-antimicrobial measures. In this article, we aimed to evaluate the effectiveness of a phytotherapeutic product composed of D-mannose, Hibiscus sabdariffa, and Lactobacillus plantarum in the prevention of infectious events following invasive urodynamic examination.Introduction and aim: The urodynamic study is an invasive examination that allows a thorough evaluation of the functional activity of the lower urinary tract (bladder, urethra). The execution of urodynamic study exposes the patient to the risk of contracting infections of the lower urinary tract. Prevention of urinary tract infections consists in the avoidance of risk factors and prophylaxis with antimicrobial and non-antimicrobial measures. In this article, we aimed to evaluate the effectiveness of a phytotherapeutic product composed of D-mannose, Hibiscus sabdariffa, and Lactobacillus plantarum in the prevention of infectious events following invasive urodynamic examination. Materials and methods: We selected 100 female consecutive patients (age 19-87 years) that underwent urodynamic invasive procedure. We prescribed 14-day therapy with D-mannose, H. sabdariffa, and L. plantarum to these 100 patients after urodynamic invasive test. After that, we have examined urine cultures and urinary symptoms through telephone interviews and hospital outpatient visits to evaluate the possible presence of urinary tract infections. Results: Urinary tract infections were observed through urine culture in 13% of the selected patients; of the 13 urinary tract infections, 9 were observed in patients with urinary tract recurrent infections in the last year and the other 4 cases were associated with patients with no urinary infection in the last year. Three women reported some urinary symptoms and underwent antibiotic therapy. The other 10 cases were classified as asymptomatic bacteriuria. Three cases were related to patients presenting with pelvic organ prolapse. Eight cases were instead related to significant post-voiding residue (&gt;100). Six patients with urinary tract infection reported constipation in the last year. All patients completed the prescribed therapy due to the affordable price of the product and no side effects have been reported. Conclusion: Our study about the administration of D-mannose, H. sabdariffa, and L. plantarum after invasive urodynamic examination underlined how this phytotherapeutic product can reduce the risk of bacteriuria and urinary tract infection in women
