PURPOSE: Transurethral resection of the prostate is the standard operation for acute urinary retention, although laser prostatectomy is reportedly effective and safe. The ClasP (conservative management, laser, transurethral resection of the prostate) study compared transurethral prostatic resection and noncontact neodymium (Nd):YAG visual laser assisted prostatectomy for treatment of acute urinary retention. MATERIALS AND METHODS: This study was a multicenter randomized controlled trial, analyses were by intention to treat and followup was at 7.5 months after randomization. Primary outcomes were treatment failure, and included International Prostate Symptom Score, International Prostate Symptom Score quality of life score, residual urine and flow rate. Secondary outcomes included complications, and duration of catheterization and hospitalization. RESULTS: A total of 148 men were randomized to transurethral prostatic resection (74) and laser (74). There were fewer treatment failures after prostatic resection (p = 0.008) and fewer men after resection required secondary surgery for poor results (1 versus 7, p = 0.029). Maximum flow rates after transurethral prostatic resection were better than after laser (mean difference 4.4 ml. per second). Comparison of symptom and quality of life scores demonstrated that any clinically significant advantage for laser could be ruled out. Patients stayed a mean of 2 extra days in the hospital after resection. The duration of catheterization was greater after laser but significantly fewer major treatment complications were found with laser therapy. CONCLUSIONS: Transurethral prostatic resection was more effective, resulted in fewer failures than laser treatment and remains the procedure of choice for men with acute urinary retention. 相似文献

Jaraj SJ, Egevad L. Formalin fixation and immunoreactivity in prostate cancer and benign prostatic tissue. APMIS 2010; 118: 383–8. For better fixation, formalin injection of radical prostatectomy (RP) specimens has been suggested. We aimed to assess its effect on immunoreactivity using immunohistochemistry (IHC). A tissue microarray of cancer and benign tissues from 42 RP specimens was constructed. Twenty‐one of the prostates had been injected with formalin prior to formalin immersion. IHC staining was performed using 15 antibodies, including nuclear and cytoplasmic markers known to be positive in prostate tissue: pan cytokeratin, P504S, high molecular weight (HMW) keratin, PSA, vimentin, actin HHF35, thioredoxin‐1, peroxiredoxin‐2, PDX‐1, BAX, p27, androgen receptor (AR) and heat shock proteins (HSP) 27, 60 and 70. Differences in staining intensity in cancer and benign tissues were compared separately except for HMW keratin. Only 7 of 29 analyses showed significant differences between groups, including 5 of 15 antibodies. The expression of AR and HSP 27 was stronger in formalin‐injected tissue, while the opposite was true for HSP 60, HSP 70 and peroxiredoxin‐2. For most antibodies, formalin injection does not significantly affect immunoreactivity in prostate tissue. The staining variability caused by inter‐ and intratumoral heterogeneity may be greater than that caused by the fixation method. 相似文献
