{"title":"Physician responsibility for removal of implants: the case for a computerized program for tracking overdue double-J stents.","authors":"M H Ather, J Talati, R Biyabani","doi":"","DOIUrl":"","url":null,"abstract":"Purpose: Ureteral stents are used in various modern urologic procedures. Although forgotten double-J (JJ) stents are an infrequent problem, they are associated with significant medical problems. Encrustation from excessive indwelling time increases morbidity and may require extracorporeal shock wave lithotripsy to free the coils of the cementing calcerous material. An effective system should be in place to ensure timely removal. The previously used \"card\" system not only is difficult to manage but has proved unreliable. We describe a computerized program that tracks JJ stents and alerts physicians about stents that need removal.Materials and methods: Two hundred eighteen patients who were stented between January 1997 and December 1998 were tracked through an integrated computerized program. This program keeps a log of all patients who received a JJ stent and determines the last date by which it should be removed. Patients are reminded if they have not returned for removal of the implant 2 weeks before it is overdue.Results: Two hundred twenty-five JJ stents were placed in 218 patients. Comparison of data between the periods before and after computer program inception showed that the incidence of stents retained longer than their expiration time decreased from 12.5% to 1.2% in the first year of the program and 1.5% in the second year of the program.Conclusions: Forgotten implants pose a significant management dilemma for physicians. Our tracking program significantly lowered the incidence of overdue JJ stents from 12.5% to 1.2% and 1.5% in the first and second years, of the program respectively (p = .00039). We propose that this technically simple program should be in place for all implants placed in patients. The problems we encountered in the smooth running of this system could be averted by incorporating several recommendations.","PeriodicalId":79536,"journal":{"name":"Techniques in urology","volume":"6 3","pages":"189-92"},"PeriodicalIF":0.0,"publicationDate":"2000-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21798320","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}

{"title":"Transrectal ultrasound-guided needle aspiration for prostatic abscesses: an alternative to transurethral drainage?","authors":"E Gan","doi":"","DOIUrl":"","url":null,"abstract":"Purpose: Prostatic abscesses traditionally are drained transurethrally. Problems of this method include the risk of anesthesia, dissemination of bacteria, incomplete drainage of multiloculated or peripheral abscesses, and retrograde ejaculation, which may not be acceptable for young patients. Prostatic abscesses can be drained under transectal ultrasound (TRUS) guidance. Multiple, peripheral, or multiloculated abscesses are visualized. No anesthesia would be required. Repeat procedures can be performed easily with minimal morbidity. The risks of dissemination and retrograde ejaculation is negligible.Materials and methods: A standard TRUS probe and a 21-gauge Chiba needle are inserted through the biopsy guide into the abscesses. Five patients underwent the procedure. Four patients had a mean follow-up of 18 months.Results: TRUS could visualize the abscess in all patients. Aspirate cultures corresponded to the urine culture except in one patient with sterile urine. Three had residual disease on repeat TRUS, but only two patients required repeat aspiration. All patients recovered and had no evidence of disease on follow-up. However, it was an average of 4 months before patients could be considered cured according to TRUS findings. Prostate volume decreased from a mean of 54 mL on diagnosis to 16 mL on follow-up. There was no hospital readmission or morbidity.Conclusions: TRUS needle aspiration for prostatic abscess is a feasible alternative to transurethral drainage. Repeat procedures may be required, but all patients recovered. There is minimal morbidity associated with the procedure; however, the recovery period may be longer.","PeriodicalId":79536,"journal":{"name":"Techniques in urology","volume":"6 3","pages":"178-84"},"PeriodicalIF":0.0,"publicationDate":"2000-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21798318","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}

{"title":"Pitfalls in the diagnosis of prostate adenocarcinoma from holmium resection of the prostate.","authors":"E Gan, A Costello, J Slavin, R G Stillwell","doi":"","DOIUrl":"","url":null,"abstract":"Purpose: Holmium laser resection of the prostate (HoLRP) provides tissue for histologic analysis that was not possible using previous coagulative laser prostatectomies. It was assumed that these tissue specimens would yield the same histologic information as specimens obtained by transurethal resection of the prostate and would be adequate for diagnosis of cancer. However, tissue subjected to laser treatment may sustain thermal injury, resulting in artifactual change. The aim of this study was to define the histologic characteristics of prostate tissue after holmium laser prostatectomy and the influence of thermal change on diagnosis of malignancy.Materials and methods: All prostate tissue was examined after HoLRP. Examination included prostate-specific antigen (PSA) staining and immunostaining for high-molecular-weight cytokeratins. Histologic features are described.Results: Thermal injury after HoLRP was more extensive than previously believed. Artifacts observed under low power consisted of glandular distortion and contraction with crowding. Higher magnification revealed clumping of the chromatin of the nucleus, resulting in hyperchromasia and irregularity of the nucleus and loss of polarity. These changes may be mistaken for malignant change. It will be difficult to detect malignancy in areas involved by thermal injury. When prostate cancer exists, grading of cancer will be affected by these artifacts. Uptake of immunohistochemical staining with PSA and high-molecular-weight cytokeratins is nonspecific in areas of injury, reducing their usefulness in these cases.Conclusions: Detection of malignancy may be compromised by thermal injury occurring after HoLRP. Preliminary preoperative transrectal ultrasound-guided biopsies may still be necessary for diagnosis of malignancy.","PeriodicalId":79536,"journal":{"name":"Techniques in urology","volume":"6 3","pages":"185-8"},"PeriodicalIF":0.0,"publicationDate":"2000-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21798319","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}

This augmented incontinence procedure is recommended for use in patients at particularly high risk of recurrence of incontinence or in patients with intrinsic sphincter deficiency who have concomitant cystocoele (paravaginal defect).Materials and methods: A prospective study was initiated to demonstrate the efficacy of this combined operative procedure that incorporates two established operative techniques.Results: Ten of 13 patients in whom this operation was performed are completely continent. They have neither stress nor urgency incontinence. They have all resumed active lifestyles. Three patients experienced postoperative problems. They had complex presentations and/or required multiple operative procedures. Two women continue to have mild urge incontinence postoperatively. One of these women has occasional urinary retention. The third woman who had a large cystocele, intrinsic sphincter deficiency, and rectal prolapse has functional obstruction postoperatively.Conclusion: Support and stability are developed at the urethrovesical angle by means of a combined operative procedure.","PeriodicalId":79536,"journal":{"name":"Techniques in urology","volume":"6 3","pages":"175-7"},"PeriodicalIF":0.0,"publicationDate":"2000-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21799635","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}
