Ureterosigmoidostomy: an outdated approach to bladder exstrophy?
1990
Long-term results among 46 children with ureterosigmoidostomy are presented. The indication for ureterosigmoidostomy had been bladder exstrophy in 40 patients, incontinent epispadias in 5 and neurogenic bladder dysfunction in 1. Of the 40 patients with bladder exstrophy 8 had undergone ureterosigmoidostomy after failure of other types of urinary tract reconstruction (6 had upper tract dilatation before ureterosigmoidostomy). Three patients with previously damaged upper urinary tracts required early postoperative conversion because of severely increasing kidney dilatation. Three other patients required conversion after a mean of 10 years to preserve kidney function. One patient died after 16…
Evolving management of adolescent varicocele
2008
Abstract Objective To review the evolution in indications for treatment and treatment modalities for adolescent varicocele at our centre, and evaluate the impact of varicocelectomy on final outcome. Patients and methods Between 1995 and 2006, we treated 242 left varicoceles. Preoperative assessment included clinical evaluation, measurement of testicular volumes, and colour-Doppler ultrasound (CDUS). A subinguinal varicocelectomy was performed in 124 patients (group A), and a laparoscopic non-artery-sparing Palomo procedure in the remaining 118 (group B). In group B patients, CDUS was also used to investigate the functional anatomy of varicocele, and all the veins found to be refluxing were …
Comprehensive laparoscopic approach to pediatric varicocele based on preoperative color Doppler ultrasound assessment
2008
Abstract: Background This study aimed to assess whether laparoscopic treatment for any kind of varicocele is possible after preoperative identification of refluxing veins by color Doppler ultrasound (CDUS). Methods At the authors'' institution, 98 patients with a median age of 11.3 years (range, 7.1-16 years) were evaluated for a left varicocele. Preoperatively, all the patients underwent ultrasound scan assessment of testicular volume and CDUS to rule out reflux into the internal spermatic vein (ISV), deferential vein, or cremasteric vein. In all the patients, laparoscopic division of the spermatic artery and veins was performed as close as possible to the internal inguinal ring. The other…
Five cases of de novo inflammatory bowel disease after orthotopic liver transplantation.
2006
Immunosuppression is currently the treatment of choice for severe inflammatory bowel disease (IBD). Thus, it was anticipated that the course of preexisting IBD should improve after orthotopic liver transplantation (OLT). Despite sufficient allograft immunosuppressive therapy, however, exacerbation of IBD or the development of de novo IBD after OLT were described in some cases, primarily in patients transplanted for end-stage primary sclerosing cholangitis (PSC). In addition, the development of de novo IBD in patients undergoing OLT for indications other than PSC was described. Evaluating our collective of 314 liver transplanted patients we found five patients transplanted for various indica…
Series of fibrinous inflammation after implantation of capsular tension rings
2014
Purpose To analyze the cause of fibrinous inflammation in eyes with capsular tension rings (CTRs) after cataract surgery. Setting Department of Ophthalmology, University Medical Center, Johannes Gutenberg-University Mainz, Mainz, Germany. Design Retrospective case series. Methods High-performance liquid chromatography was implemented to eliminate impurities. One CTR was explanted for microbiologic examination. The pH values of the CTR and the storage solution were analyzed, Seldi and Maldi tests were performed, as well as toxicity tests with immortal cell lines. Material batches were analyzed. The organic carbon content of CTRs, detergents, and storage solutions was checked. The presence of…
Preoperative risk factors for postoperative delirium (POD) after urological surgery in the elderly
2011
The aim of this observational study was to investigate the occurrence of postoperative delirium (POD) in elderly patients undergoing urological surgery and to identify those factors associated with delirium. Ninety consecutive patients (81 males and 9 females; average age of 74.3 ± 0.40 years), undergoing urological surgery in University-Hospital Urological Clinic were selected. Personal, medical, cognitive and functional data, biochemical parameters, preoperative medications, conduct of surgery and anesthesia and details of hemodynamic control were collected as predictors of delirium. After surgery, the subjects were divided on the basis of delirium onset within a week observation period. …
Risk factors for postoperative delirium after colorectal surgery for carcinoma
2011
Background and aim: Data regarding the incidence and risk factors for postoperative delirium (PD) after gastrointestinal surgery are heterogeneous because they include both benign and malignant disease. The aim of this study was to investigate the incidence and risk factors for PD in 100 consecutive patients over 65 years who underwent colorectal surgery for carcinoma. Methods: Pre-operative cognitive function was assessed using the Mini Mental State Examination. The onset of PD was diagnosed by the Confusion Assessment Methods administered to the patients every 12 h starting from the first postoperative day to discharge. The severity of PD was also evaluated with the Delirium Rating Scale.…
A simple technique of oblique anastomosis can prevent stricture formation in primary repair of esophageal atresia
2012
Abstract Background Anastomotic stricture is an important problem after esophageal atresia (EA) repair. This study evaluates a technique of oblique esophageal anastomosis without use of a flap in order to prevent stricture formation. Methods Medical records of 16 patients (14 with EA type III and 2 with EA type IV Ladd-Gross classification) who underwent primary repair of EA at birth without anastomotic tension were reviewed, evaluating long-term follow-up results. All patients were studied with esophageal contrast study, pH-multichannel intraluminal impedance, and endoscopy. The incidence of complications and their management were analysed. Results Contrast esophagogram and esophagoscopy a…
Contrast-induced Nephropathy after Percutaneous Coronary Intervention in Simple Lesions: Risk Factors and Incidence are Affected by the Definition Ut…
2011
Aim To compare the incidence, and risk factors, in-hospital and at the 18-month prognosis of contrast-induced nephropathy (CIN) according to the definition utilized: as an increase in serum creatinine (Scr) ≥0.5 mg/dL (CIN 1) or as an increase in Scr ≥25% above baseline values (CIN 2). Methods and Results We prospectively evaluated CIN according to two different definitions in 150 patients who underwent percutaneous coronary intervention (PCI) in simple lesions employing a low-medium dose of contrast media. Incidence of CIN was higher using the CIN 2 definition than CIN 1 (9.3% vs. 4%; p=0.0133). Patients with CIN 1 had a higher incidence of chronic kidney disease (CKD) (66.7% vs. 13.9%; p=…
Changes inα-tocopherol and retinol levels during cardiopulmonary bypass correlate with maximal arterial partial pressure of oxygen
2007
Cardiopulmonary bypass (CPB) is associated with oxidative stress. This study examined antioxidant levels in adults undergoing CPB surgery and their correlation with clinical variables. Arterial blood samples were obtained from 27 patients undergoing CPB. The time-course variation of vitamin C (spectrofluorimetry), alpha-tocopherol and retinol (HPLC) levels were determined. Plasma vitamin C rose initially but gradually decayed during reperfusion until 60% reduction of baseline values post-surgery. alpha-Tocopherol and retinol were reduced along CPB with post-operative values approximately 25% lower than baseline. No significant changes were found for selenium and glutathione peroxidase. PaO(…
