Objective
To compare the efficacy and tolerability of the &agr;1A‐subtype selective drug tamsulosin with the non‐subtype‐selective agent alfuzosin in the treatment of patients with lower urinary tract symptoms (LUTS) suggestive of bladder outlet obstruction (BOO), often termed symptomatic benign prostatic hyperplasia (BPH).
Patients and methods
The study comprised 256 patients with benign prostatic enlargement and LUTS suggestive of BOO (symptomatic BPH) who received tamsulosin 0.4 mg once daily or alfuzosin 2.5 mg three times daily during 12 weeks of treatment. The response was assessed by measurements of maximum urinary flow rate (Qmax ), a symptom score (Boyarsky) and blood pressure at regular intervals.
Results
Tamsulosin and alfuzosin produced comparable improvements in Qmax and total Boyarsky symptom score. Both treatments were well tolerated with respect to adverse events. Tamsulosin had no statistically significant effect on blood pressure compared with baseline but alfuzosin induced a significant reduction in both standing and supine blood pressure, compared with baseline (P<0.05).
Conclusion
Tamsulosin is the first adrenoceptor antagonist that is selective for the &agr;1A‐subtype; this specificity may explain its lack of effect on blood pressure compared with alfuzosin, an agent that is not receptor subtype specific. Moreover, this finding may partly explain why tamsulosin, in contrast to other currently available &agr;1‐adrenoceptor antagonists, can be administered without dose titration. Another advantage compared with alfuzosin (and prazosin) is the once‐daily dosing regimen of tamsulosin.
The posterior and anterior fixation of the vesicourethral anastomosis during RRP results in an intact sphincteric mechanism, because no stretch is applied to the urethra, resulting in earlier continence.
Robot-assisted procedures are slowly invading minimally invasive urologic surgery. When superior visibility, meticulous dissection, or complex reconstruction is needed, robotic surgery may offer benefits over conventional laparoscopy. We report the use of the da Vinci robotic system for laparoscopic psoas hitch-supported ureteral reimplantation. We believe this procedure was facilitated technically compared with conventional laparoscopy.
Recent reports have demonstrated that robot-assisted laparoscopic cystectomy is technically feasible. We report technical and functional results of a large series of patients undergoing laparoscopic cystectomy with the da Vinci surgical system (DVSS). A total of 27 patients (24 males) underwent laparoscopic radical cystectomy with the DVSS (intuitive surgical) between January 2004 and December 2005. Indications for cystectomy were muscle-invasive transitional cell carcinoma (TCC) or leiomyosarcoma of the urinary bladder (n = 24) and bladder shrinking following prior radiotherapy for TCC. A pelvic lymphadenectomy was a routine part of the procedure. Urinary diversions were ilieal conduits (n = 19) and ileal neobladders (n = 8). Mean operating time was 340 min (range 150–450) with a mean blood loss of 301 ml (range 50–550). The mean number of lymph nodes retrieved during lymphadenectomy was 23. Surgical margins were negative except in one case. After a mean follow-up of 10.2 months, two perioperative (anastomotic leakage, adhesions) and three postoperative complications (ileus, intestinal fistula, urinary tract obstruction) occurred. Six out of seven patients reported satisfying erectile function following nerve-sparing surgery. Day-time continence was completely restored after a mean 3.5 months in seven of eight patients. Robot-assisted laparoscopic cystectomy is a safe procedure. Satisfying functional and oncological short-term results can be achieved within acceptable operating time limits.
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.
