We performed a retrospective study to assess this practice.Materials and methods: The medical records of 180 patients subjected to PCN for various reasons between October 1991 and July 1998 were reviewed. This represents a subset of patients in whom PCN was performed by an experienced interventional radiologist at our institution. Patients were excluded if they had a history of active liver disease, hematologic or bleeding disorder, current use of heparin or warfarin, or platelet count <100,000. The remaining 160 patients were separated into two groups. Group 1 consisted of 153 patients with a normal prothrombin time (PT) and partial thromboplastin time (PTT). Group 2 comprised 7 patients with an abnormal PT or PTT. Demographic and laboratory data including PT, PTT, complete blood, and platelet counts were analyzed to determine if a hemorrhagic complication could be predicted by an abnormal PT or PTT.Results: In group 1 the mean PT was 12.2 seconds and the mean PTT was 25.0 seconds; in group 2 the mean PT was 13.9 seconds and the mean PTT was 30.3 seconds. The hemorrhagic complication rates were not statistically different between the two patient cohorts (p = .203). Demographic and standard laboratory data were not predictive of abnormal coagulation parameters.Conclusions: Screening coagulation studies are unnecessary in the standard patient subjected to PCN.","PeriodicalId":79536,"journal":{"name":"Techniques in urology","volume":"6 3","pages":"205-7"},"PeriodicalIF":0.0,"publicationDate":"2000-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21798324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These modalities do not allow retrieval of prostate tissue for histologic review. The goal of our study was to assess the value of transurethral biopsies in detecting prostate cancer in men who would undergo surgical intervention for BPH.Materials and methods: Between September 1997 and January 1999, 422 men undergoing transurethral resection of the prostate (TURP) had transurethral biopsies obtained before completing the TURP. Pathology reports as well as prostate-specific antigen (PSA) results were reviewed and analyzed to determine when cancer was present.Results: Pathological examination revealed that cancer was found in 53 men (12.5%). The transurethral biopsies detected cancer in 32 of 53 (60.4%). No cancers were found in the transurethral biopsy specimen only. Of the 21 cancers missed by transurethral biopsy, 7 were stage T1b. PSA level >10 ng/mL increased the likelihood of finding cancer.Conclusions: Transurethral biopsy sampling is unreliable for detecting prostate cancer in men with clinically significant BPH. Significant cancers are missed if transurethral biopsies are used to determine the presence of carcinoma before minimally invasive surgical therapy for BPH.","PeriodicalId":79536,"journal":{"name":"Techniques in urology","volume":"6 3","pages":"201-4"},"PeriodicalIF":0.0,"publicationDate":"2000-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21798323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The various indications for lower urinary tract reconstruction in this patient population included malignancy (4), neurogenic bladder (11), and urethral dysfunction (8). The continence mechanism is provided by the ileocecal valve, with tapering of the distal ileal segment with an absorable stapling device and then securing the catheterizable ileal segment to the serosa of the cecum along an opened taenia to provide an additional level of continence to the ileocecal valve.Results: Continence was achieved in 83% (19 of 23) of patients. Two patients required revision and are now dry, and two patients have not undergone revision and remain wet. No patients have had problems with difficult or traumatic catheterization of the limb or peristomal hernia. One case of stomal stenosis was identified and treated with an outpatient revision.Conclusions: This technique for construction of a continence mechanism for a continent cutaneous urinary reservoir is simple to create, reliable, and without excess morbidity.","PeriodicalId":79536,"journal":{"name":"Techniques in urology","volume":"6 3","pages":"167-71"},"PeriodicalIF":0.0,"publicationDate":"2000-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21799633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Contradictory reports on the association between serum IGF-1 level and prostate cancer have been highlighted in the recent literature. The purpose of this study was to investigate the relation between serum levels of IGF-1 and prostate cancer.Materials and methods: We analyzed a population of 57 patients who underwent radical prostatectomy (RP) for adenocarcinoma. Serum samples were collected before RP (T0), 6 months after RP (T6), and from 39 age-matched controls. IGF-1 levels were determined by the active IGF-1 Elisa kit (Diagnostic Systems Laboratories, Inc.). Parallel samples were evaluated for prostate-specific antigen (PSA) levels. Data between groups were analyzed using Welch's t-test and levels before RP and after 6 months were compared by paired t-test.Results: The normal mean serum IGF-1 for case patients at T0 (124.6+/-58.2 ng/mL) was significantly lower than the control subjects (157.5+/-70.8 ng/mL; p = .0192). The normal mean serum IGF-1 for case patients at T0 (124.91+/-58.6 ng/mL) also was significantly lower when it was compared with the T6 group (148.49+/-57.2 ng/mL; p = .0056). No association was found between IGF-1 and PSA blood levels, or IGF-1 and patient weight (p = 0.2434). An inverse relation between IGF-1 levels and age in the normal controls (p = .0041) was observed.Conclusion: Findings of this study indicate a significant association between low serum levels of IGF-1 and prostate cancer.","PeriodicalId":79536,"journal":{"name":"Techniques in urology","volume":"6 3","pages":"236-9"},"PeriodicalIF":0.0,"publicationDate":"2000-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21800047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we correlate presence of bacterial signal with response to therapy.Materials and methods: EPS and first voided urine (VB1) from 47 men with CPPS were analyzed by polymerase chain reaction (PCR) for bacterial signal using universal primers specific for bacterial 16S rRNA. Signal was considered positive if found only in the EPS sample, or if at least 10x stronger in the EPS than in VB1. All patients were treated with antibiotic therapy.Results: Thirty-three patients were category IIIa (nonbacterial prostatitis) and 14 were category IIIb (prostatodynia). Seventeen of the 33 category IIIa patients had positive localizing cultures for gram-positive bacteria. However, a positive bacterial signal was detected in 23 EPS samples by 16S rRNA PCR. This signal was found in 14 of 17 culture-positive patients, 7 of 16 of the remaining category IIIa patients, and 2 of 14 of category IIIb patients. No patient with negative bacterial signal improved with antibiotic therapy (negative predictive value 100%). Thirteen patients with positive bacterial signal improved with antibiotic therapy.Conclusions: In men with category III chronic prostatitis/CPPS, bacterial signal detected by PCR can help predict response to antimicrobial therapy.","PeriodicalId":79536,"journal":{"name":"Techniques in urology","volume":"6 3","pages":"240-2"},"PeriodicalIF":0.0,"publicationDate":"2000-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21800048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
