Transvesical ONB is a safe and effective method of ONB before TURBT. This method is feasible by urologists and promising even without nerve stimulation and only by anatomic landmarks.
Wagener's granulomatosis (WG) is a rheumatologic disease with unknown etiology which renal and pulmonary involvement is commonly seen. Renal involvement in Wagener's granulomatosis represents as a segmental necrotizing glomerulonephritis which is not visible with imaging techniques and usually presents with proteinuria, microhematuria, and hypertension. A rare presentation of the disease is a renal mass which can be mistaken as renal tumors, abscess, or lymphoma. We report a 22-year-old female with flank pain and fever who was admitted in our hospital. The patient underwent renal tumor biopsy and diagnosed with Wagener's granulomatosis in pathologic staining. The aim of this work is introduction of Wagener's granulomatosis as a differential diagnosis of renal tumors, to prevent unnecessary interventions and delayed treatment.
Background:Tumor growth requires expansion and development of vascular network. An increase in Gleason score is representative of an increase in tumor invasion and extent. In this study, the relationship between Gleason score and vascular characteristics of needle biopsy samples in prostate cancer patients has been evaluated.Materials and Methods:We evaluated vascular characteristics including density and size of vessels; and percentage of vessels with irregular shape in 62 cancer-positive samples obtained by prostate needle biopsy under ultrasound guide, and compared them to Gleason score.Result:Gleason scores of 23 patients were ≤6; Gleason scores of 18 patients were 7 and 21 patients had their Gleason score from 8 to 10. An increase in Gleason score was associated with increased vascular density (P < 0.0001), increased percentage of vessels with irregular shape (P < 0.02) and decreased average vascular diameter (P < 0.015), from which the relationship with vascular density was clearer and more evident.Conclusion:Vascular morphological characteristics can be representative of angiogenic potential of prostate cancer which is required for tumor progression. As Gleason score can prognosticate the behavioral characteristics of prostate cancer in future, vascular characteristics may also be able to express tumor behavior. With attention to vascular characteristics in biopsy samples and apart from Gleason score, we may also be able to divide patients into other subtypes in a way being helpful for the establishment of treatment plan.
Background:The aim of this study is the caparison of the complications rate among the patients which underwent nephrostomy removal with and without performing nephrostography.Materials and Methods:Between October 2010 and November 2011, 200 patients who underwent standard percutaneous nephrolithotomy (PCNL) procedures were included in this study. The patients were randomly assigned into two groups, Group A (n = 100) did not undergo the antegrade nephrostography on postoperative day 2 and the patients were discharged keeping the nephrostomy until postoperative day 3, while in Group B (n = 100) the nephrostomy tube was removed on postoperative day 3 after antegrade nephrostography demonstrating ureteral drainage down to the bladder. Postoperative complications in both groups were recorded and compared between two groups.Results:A total of 200 patients were treated with standard PCNL. The persistent leakage of urine after removal of the nephrostomy tube was encountered in 5 (5.0%) and 3 (3%) of patients in Groups 1 and 2, respectively. Urinary leakage was resolved with conservative management in 3 and 2 patients of Groups 1 and 2, respectively, but a double-J stent was inserted in 2 and 1 patients in each group because of persistent leakage of urine more than 1-week. The two groups show comparable complications such as prolonged urinary leakage which managed in a similar manner, however, postoperative hospital stay was lesser in Group 1.Conclusion:Our results revealed postoperative performing nephrostogramy before tube removal changed the planning of complications such as prolonged urinary leakage and could be omitted in cases.
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.
