The morbidity and efficacy of PCNL are similar in patients who have had previous open nephrolithotomy and those having no previous surgery. Previous open surgery does not affect the success of PCNL.
Objective. To assessment the role of preoperative neutrophil-lymphocyte ratio and postoperative lymph node density in predicting prognosis in patients undergoing radical cystectomy for bladder cancer. Material and Methods. Preoperatively, neutrophil and lymphocyte counts as well as neutrophil-lymphocyte ratios were recorded in 201 patients who underwent radical cystectomy for bladder cancer. Patients with an infection were excluded. Based on the pathology reports, the number of positive lymph nodes was divided by the total number of lymph nodes to calculate lymph node density. Results. The mean follow-up duration was 37.22 ± 35.922 months in patients without lymph node involvement and 27.75 ± 31.501 months in those with lymph node involvement (P = 0.015). Median lymph node density was 17% (4–80) in patients with lymph node involvement. There was no difference according to lymph node density lower than 17% and greater than 17% (P = 0.336). There was no significant difference between patients with an NLR below or above 2.5 in terms of overall survival (P = 0.702). Pathological T stage was associated with survival (P = 0.004). Conclusion. In patients undergoing RC for bladder cancer, lymph node density and preoperative NLR were not found to be independent predictors of prognosis.
Introduction: Most upper or middle ureteral stones are treated with shock wave lithotripsy or endoscopic techniques. In rare cases the ureteral stones are treated with open surgery after failure of first-line treatments. Retroperitoneoscopy is a minimally invasive alternative to open surgery. Patients and Methods: Between May 1995 and January 2001, twenty-one patients underwent retroperitoneoscopic ureterolithotomy. The stones in upper and middle ureter were large and impacted (5 patients) or not fragmented after shock wave lithotripsy (16 patients). A balloon dissector was placed and infiltrated with 800 ml air in the retroperitoneal space. Three 10-mm trocars were used. The pressure was kept at 15 mm Hg by carbon dioxide insufflation. The stones were extracted from the ureter using a laparoscopic stylet. Results: The stones in 17 patients were successfully removed in a median operating time of 105 (min–max 45–190) min. Urine extravasation in all cases and pnomoscrotum in 2 cases were observed as postoperative complications. The median hospital stay was 6 (min–max 3–22) days with minimal analgesic requirement. Conclusion: Retroperitoneoscopic ureterolithotomy is a useful and effective alternative treatment technique to open surgery when first-line treatments have failed or are unlikely to be effective.
Step-wise SWL yielded better outcomes than conventional SWL without increased morbidity. Stepwise SWL can be considered as a management option for urinary calculi.
This study aimed at determining the choice and administration duration of ideal antibiotic prophylaxis before percutaneous nephrolithotomy (PNL) operation, a treatment modality for nephrolithiasis. The study included 90 patients who had no internal problem, yet had a negative urine culture and underwent a PNL operation. We compared infection rates between ciprofloxacin and ceftriaxone groups and their subgroups. The results showed no statistical difference between ciprofloxacin and ceftriaxone groups in terms of systemic inflammatory response syndrome (SIRS) (CIPP = 0.306, CTX P = 0.334. As a result of this study no statistical difference was observed between ciprofloxacin and ceftriaxone in terms of SIRS. It seems, however, reasonable to choose ceftriaxone, considering antibiotic sensitivity of microorganisms and detection of three cases accepted as urosepsis in the ciprofloxacin group. As there is no difference between short, and long-term prophylactic use of these antibiotics, preference of short-term prophylaxis for patients with no risk of infection will be important to avoid inappropriate antibiotic usage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
