Impact on sexual function of holmium laser enucleation versus transurethral resection of the prostate: results of a prospective, 2-center, randomized trial.

PURPOSE: We compared the impact of HoLEP and TURP on sexual function. MATERIALS AND METHODS: Between January 2002 and January 2003, 120 patients with a mean age +/- SD of 65.2 +/- 7.1 years who had benign prostatic hyperplasia were enrolled in this 2-center, prospective, randomized study. A total of 60 patients with a mean age of 65.25 +/- 6.9 years underwent HoLEP (group 1) and 60 with a mean age of 64.18 +/- 7.2 years underwent TURP (group 2). Patients were assessed before surgery, and at 12 and 24-month followup visits. Subjective symptoms were scored by the International Prostate Symptom Score, the International Prostate Symptom Score quality of life question, IIEF, 10 nonvalidated general assessment questions, physical examination, serum prostate specific antigen and transrectal ultrasonography. RESULTS: A total of 32 patients (53.3%) in group 1 and 31 (51.6%) in group 2 reported various degrees of erectile dysfunction before surgery according to the IIEF-EF score. Differences between preoperative and postoperative orgasmic domain scores in each group were significant (p <0.001). A slight but not significant increase in the mean IIEF-EF domain score was reported in each group at postoperative assessments without any difference between the 2 surgical approaches. According to general assessment question analysis the prevalence of subjectively reported postoperative retrograde ejaculation was significantly higher than at baseline assessment in the 2 groups with no differences between the 2 surgical procedures. CONCLUSIONS: TURP and HoLEP significantly lowered the IIEF orgasmic function domain with no differences between techniques. This was caused by retrograde ejaculation. Marginal, nonsignificant erectile function improvement was reported after surgery in the 2 groups.

[Optimization of hydrodynamic conditions in transurethral resection of benign prostatic hyperplasia].

Water intoxication remains a serious complication of transurethral resection (TUR) occurring more frequently in patients with large-size benign prostatic hyperplasia (BPH) and in those who was operated for more than 1 hour. An advanced irrigation system employing mechanical valve "Floval" and active aspiration provides controlled irrigation of the bladder preventing spontaneous rise of intravesical pressure in conducting TUR in BPH patients.

Subacute hyponatraemia after transurethral resection of the prostate.

We present a case of subacute hyponatraemia which developed 3 days after a transurethral resection of the prostate. Symptoms consisted of nausea, vomiting and headache. Release of vasopressin due to excessive surgical bleeding, combined with liberal oral and intravenous administration of sodium-free fluids, was considered to be the cause.

'Will you be doing my operation doctor?' Patient attitudes to informed consent.

BACKGROUND: As part of the consent process, it is part of a doctor's duty of care to reveal any material risk. Depending upon the level of supervision, whether the operating surgeon is a trainee may be such a risk, but in our experience this is not routinely discussed with patients pre-operatively. We set out to discover patients' attitudes to being operated on by trainee urological surgeons. PATIENTS AND METHODS: A total of 101 completed questionnaires were received from patients (90 male, 11 female, mean age 72 years) undergoing transurethral resection of the prostate (TURP), transurethral resection of a bladder tumour (TURBT) or cystodiathermy on various aspects of their attitudes to being operated on by junior doctors as part of training. RESULTS: The response rate was 77%. Of the respondents, 94 patients (91%) thought that junior doctors should perform surgery as part of their training. Only 11 of 73 (15%) said they would be happy for a junior doctor, competent to perform the procedure, to operate unsupervised. Of 98 patients, 80 (82%) thought they should be told if the operation was going to be performed by a junior doctor, and 85 (87%) that they should be told their name and designation. CONCLUSIONS: For consent to be 'informed', the experience and identity of the surgeon should be made known to patients. Most patients are happy to be operated on by a junior doctor under consultant supervision, but would want to be told and know their name and status.

Mortality and reoperation after open and transurethral resection of the prostate for benign prostatic hyperplasia.

As part of an ongoing effort to evaluate alternative treatments for benign prostatic hyperplasia, we compared the outcomes of transurethral resection of the prostate with those of open prostatectomy. Men undergoing prostatectomy in Denmark (n = 36,703), Oxfordshire, England (n = 5284), and Manitoba, Canada (n = 12,090), were identified retrospectively through administrative data and followed for up to eight years. The cumulative percentage of patients undergoing a second prostatectomy was substantially higher after transurethral than after open prostatectomy (12.0 vs. 4.5 percent in Denmark, 12.0 vs. 1.8 percent in Oxfordshire, and 15.5 vs. 4.2 percent in Manitoba). The long-term age-specific mortality rates associated with transurethral prostatectomy as compared with open prostatectomy were also elevated in each country. The data on 1650 Canadian patients were used to investigate the contribution of coexisting morbid conditions to the elevated risk of death. The relative risk was 1.45 (95 percent confidence interval, 1.15 to 1.83) before risk adjustment and 1.45 (95 percent confidence interval, 1.15 to 1.84) after adjustment; the higher mortality was seen among low-risk as well as high-risk patients. These findings suggest that transurethral prostatectomy is less effective in overcoming urinary obstruction than the open operation. Our data also raise the possibility that transurethral prostatectomy may result in higher long-term mortality, although we cannot rule out potential confounding effects of unmeasured characteristics of patients.

The natural history of lower urinary tract dysfunction in men: the influence of detrusor underactivity on the outcome after transurethral resection of the prostate with a minimum 10-year urodynamic follow-up.

OBJECTIVES: To assess the long-term outcome of the efficacy of transurethral resection of the prostate (TURP) in men with detrusor underactivity (DUA), a cause of lower urinary tract symptoms (LUTS) in a significant minority of men. PATIENTS AND METHODS: Neurologically intact men with LUTS, who were investigated in our department between 1972 and 1986, diagnosed with DUA and who underwent surgical intervention, were invited for a repeat symptomatic and urodynamic assessment. Identical methods were used, allowing direct comparison of the results. RESULTS: In all, 224 men were initially diagnosed with DUA; 87 (39%) of these died in the interim and 22 followed had a TURP, with a mean follow-up since surgery of 11.3 years. There were no significantly sustained reductions in any symptoms. There was a small but significant reduction of questionable clinical significance in the bladder outlet obstruction index, but this did not translate into an improved flow rate. Comparison with 58 age-matched patients with DUA who remained untreated showed no significant advantage of surgical intervention in the long-term; on the contrary, there was more chronic retention in those who had had surgery. CONCLUSIONS: There are no long-term symptomatic or urodynamic gains from TURP in men shown to have DUA. The results of TURP in men with DUA are important, as urologists who surgically treat patients based on the symptoms and uroflowmetry alone will do so in a significant minority of men with DUA. These results strengthen the argument for a routine preoperative urodynamic assessment.

Use of cyclooxygenase-2 inhibitor for prevention of urethral strictures secondary to transurethral resection of the prostate.

OBJECTIVES: To analyze whether the addition of a cyclooxygenase (COX)-2 inhibitor after transurethral resection of the prostate (TURP) offers an advantage compared with TURP alone in reducing postoperative urethral strictures. At urethroscopy, stenosis of the urethra with a circumference of less than 19 mm was defined as stricture. METHODS: This was a prospective, unblinded, randomized, single-center study. Between December 2001 and December 2003, 96 consecutive men with benign prostatic hyperplasia underwent TURP. After TURP, patients were randomly assigned to receive or not receive a COX-2 inhibitor (rofecoxib 25 mg/day). In the group given the COX-2 inhibitor, the therapy was started at catheter removal and continued for 20 days. Follow-up was performed on an outpatient basis after 1 month. A diagnosis of postoperative urethral stricture was assessed during a follow-up of 12 months. RESULTS: At the 1-month visit, the mean and median improvement in the peak urinary flow rate from preoperative values was +6.25 +/- 3.76 mL/s (median 7.30) in the no COX-2 inhibitor group and +9.42 +/- 3.06 mL/s (median 8.75) in the COX-2 inhibitor group. The improvement was significantly (P < 0.0001) greater for the group treated with the COX-2 inhibitor. At 1 year of follow-up, a urethral stricture had been diagnosed in 8.3% of all cases; in particular, in 17% and 0% of cases in the no COX inhibitor group and COX-2 inhibitor group, respectively. Post-TURP COX-2 inhibitor therapy was significantly (P = 0.0039) and inversely (r = -0.2876) associated with urethral stricture development. CONCLUSIONS: We suggest that limited postoperative treatment with a COX-2 inhibitor can effectively prevent post-TURP urethral stricture development by specifically interfering with the inflammatory processes that can precede scar formation.

Symptomatic and urodynamic improvement by oral distigmine bromide in poor voiders after transurethral resection of the prostate.

UNLABELLED: OBJECTIVESz: To study the clinical and urodynamic effects of oral distigmine bromide (distigmine) by using pressure-flow studies in patients who were persistently poor voiders after transurethral resection of the prostate. METHODS: The study included 14 poor voiders after transurethral resection of the prostate who were 50 years old or older. Their poor voiding conditions were characterized by a mean International Prostate Symptom Score of 18.9 or a mean quality-of-life index of 4.6 and a mean maximum flow rate of 8.9 mL/s. All patients underwent symptomatic and urodynamic investigations before and after 4 weeks of daily treatment with 15 mg oral distigmine. RESULTS: In the baseline pressure-flow studies, all patients had weak detrusor contractility as demonstrated by Schäfer's diagram and the maximum Watts factor but did not have bladder outlet obstruction. They had symptomatic improvements after oral distigmine treatment, with the International Prostate Symptom Score reduced to a mean of less than 10 and the quality-of-life index reduced to a mean of less than 3. In the urodynamic investigations, the maximum flow rate improved significantly to a mean of more than 12 mL/s in parallel with a significant increase in the maximum Watts factor. Detrusor contractility according to Schäfer's diagram also tended to improve after oral distigmine treatment. However, no significant changes were found in any of the parameters of bladder outlet obstruction. CONCLUSIONS: Poor voiders after transurethral resection of the prostate who have weak detrusor contractility without bladder outlet obstruction may benefit clinically from treatment with distigmine because of its efficacy in increasing detrusor contractility without enhancing bladder outlet obstruction.

High-dose-rate intensity-modulated brachytherapy with external beam radiotherapy for prostate cancer: California endocurietherapy's 10-year results.

PURPOSE: To present the long-term outcome and morbidity of high-dose-rate brachytherapy (HDR-BT) combined with external beam radiotherapy (EBRT) for localized prostate cancer. METHODS AND MATERIALS: Between September 1991 and December 1998, 209 consecutive patients with no prior androgen suppression were treated with HDR-BT plus EBRT. The median follow-up was 7.25 years (range, 5-12 years). The patients were stratified into three risk groups: low (Stage T2a or less, Gleason score </=6, and prostate-specific antigen [PSA] level </=10 ng/mL), intermediate (Stage T2b,c, Gleason score 7, and PSA level 10-20 ng/mL), and high (Stage T3, Gleason score 8-10, and PSA level >20). Four definitions of PSA progression were compared with the general clinical failure outcome: the American Society for Therapeutic Radiology and Oncology (ASTRO) definition, nadir plus 2.0 ng/mL, two consecutive rises >/=0.5 ng/mL, and PSA level >0.2 ng/mL. Morbidity was scored using Radiation Therapy Oncology Group criteria. RESULTS: The general clinical control rate was 90% (188 of 209), and the general clinical failure rate was 10% (21 of 209). The overall survival rate was 79%, and the cause-specific survival rate was 97%. The PSA progression-free survival (ASTRO definition) rate was 90%, 87%, and 69% for the low-, intermediate-, and high-risk groups, respectively. The nadir plus 2 ng/mL and two rises >/=0.5 definitions correlated better with the actual clinical outcome than did the ASTRO and PSA >0.2 ng/mL definitions. The rate of Grade 3 and 4 late urinary morbidity was 6.7% and 1%, respectively, mostly occurring in patients who had undergone post-RT transurethral prostate resection. No late Grade 3 or 4 rectal morbidity developed. The sexual potency preservation rate was 67%. CONCLUSION: Our 10-year results have demonstrated HDR-BT plus EBRT is a proven treatment for all stages of localized prostate cancer. The morbidity was low, but post-RT transurethral resection should be avoided.

Total fluid balance during transurethral resection of the prostate.

All fluids given and recovered during and for 24 hours following transurethral resections of the prostate (TURP) in 35 elderly men were recorded and compared with the health status of the patient. The results show that irrigating fluid absorption and the choice of a crystalloid or a colloid solution for intravenous fluid supplementation were the most important factors governing the total fluid balance at the end of TURP as well as 2 hours later. At 24 hours after the operation, the absorption of irrigating fluid during TURP and the presence of cardiac disease promoted retention of fluid. Impaired kidney function and serum cortisol concentration did not, however, correlate with the fluid balance.

Antibiotic prophylaxis for patients undergoing transurethral resection of the prostate.

OBJECTIVES: To evaluate the prevention of urinary tract infections (UTIs) after transurethral resection of the prostate (TURP) in a prospective randomized study using a quinolone antibiotic (fleroxacin) to compare the efficacy of: (1) a single oral dose, (2) a single intravenous (IV) dose, and (3) an extended regimen consisting of an initial IV dose followed by oral therapy until removal of the urinary catheter, but for less than 6 days. METHODS: We excluded from study patients who received antimicrobial agents within 48 hours of surgery. Single-dose prophylaxis consisted of 400 mg of fleroxacin given either orally or intravenously. The extended regimen consisted of an initial 400 mg IV dose followed by 400 mg oral each day (patients older than 75 years, or with a creatinine clearance less than 40 mL/min, received 200 mg/day). UTI was defined as clinical evidence of infection plus the presence of more than 10 white blood cells (WBC)/mm3 in any urine specimen plus the presence of more than 10(4) cfu/mL in midstream urine specimens or more than 10(2) cfu/mL in catheter specimens. RESULTS: Prior to TURP, 30% (25/84) of the patients had a urethral catheter in situ and 12% (3/25) of these patients had bacteriuria. Only 1 patient developed a UTI and that was 22 days after a TURP (intergroup comparisons, Fisher's exact test greater than 0.05). There were no instances of urosepsis. CONCLUSIONS: A single oral dose of a fluoroquinolone agent provided optimum prophylaxis for patients undergoing TURP.

Irrigation fluid absorption during transurethral resection of the prostate: spinal vs. general anaesthesia.

BACKGROUND: The absorption of irrigation fluid during transurethral resection of the prostate (TURP) is determined primarily by hydrostatic pressure in the bladder and prostatic venous pressure. In comparison to spontaneously breathing patients, patients undergoing mechanical ventilation with positive pressure have a raised central venous pressure and a reduced venous return, both of which can influence intravascular absorption. The purpose of the prospective study was to compare the effects of general (GA) and spinal anaesthetic (SA) techniques on the perioperative absorption of irrigating fluid in patients undergoing TURP. METHODS: Forty patients undergoing TURP were randomised and assigned either to group GA or SA. Irrigating fluid absorption was traced by adding 1.5% (w/v) ethanol to the irrigating fluid. Perioperative blood ethanol concentration (BEC), haemoglobin concentration, haematocrit, serum sodium concentration and central venous pressure (CVP) were measured at 10-min intervals during TURP and at 30-min intervals while patients were recovering. Absorption routes were indexed by the BEC and changes in serum sodium concentrations. Where the BEC was greater than 0.05 mg.mL-1, absorption of irrigating fluid was assumed. For assessing the volume of irrigating fluid absorbed, the maximum BEC, the absorption rate, the area under the BEC curve (AUC), and the volumes calculated according to the Hahn nomogram (Volin) for each patient were taken into consideration. RESULTS: There were 15 cases of irrigating fluid absorption in patients receiving GA (75%), and 11 in those receiving SA (55%). CVP was significantly lower in spontaneously breathing patients with SA as compared to those with GA (P < 0.05). In patients with irrigating fluid absorption the maximum BEC (P < 0.02), as well as the rate of irrigant fluid absorption (P < 0.01), were significantly higher amongst patients receiving SA. In this group, the calculated area under the curve and the absorbed fluid volumes determined with the nomogram were significantly increased (P < 0.05). CONCLUSION: The absorption of irrigation fluid during the TURP is significantly more marked amongst spontaneously breathing patients with regional anaesthesia in comparison to patients undergoing general anaesthesia with positive pressure ventilation. The markedly lower central venous pressure before the start of irrigation should be considered as a possible cause of this effect.

Oral ciprofloxacin as prophylaxis in transurethral resection of the prostate.

A new quinolone antibacterial, ciprofloxacin, was evaluated as oral prophylaxis for transurethral resection of the prostate in a randomised controlled trial. A 3-day course of perioperative ciprofloxacin 250 mg twice daily reduced the post-operative infection rate, the post-operative hospital stay and the frequency of infective complications. Ciprofloxacin was well tolerated and no significant haematological or biochemical side effects were detected.

Early removal of catheter following transurethral resection of the prostate.

This study was conducted on 83 patients who underwent an uncomplicated transurethral resection of the prostate for carcinoma or benign hyperplasia. In all cases the urethral catheter was removed within 24 h of surgery. Only 2 patients failed to void because of clot retention. The total hospital stay was 3 days in 67 patients. There were no significant complications due to early removal of the catheter.

Does catheter traction reduce post-transurethral resection of the prostate blood loss?

OBJECTIVE: To determine if traction on a catheter after transurethral resection of the prostate (TURP) reduces post-operative bleeding. PATIENTS AND METHODS: This prospective trial included 115 consecutive patients undergoing TURP. After resection patients were randomly selected to have either traction (57) or no traction (58) on the catheter for 30 min. Blood loss was measured during and for 2 h after the operation. A simple method for applying constant traction is described. RESULTS: Catheter traction reduced post-operative bleeding while applied, but had no further effect after the removal of traction. CONCLUSION: Catheter traction is a useful technique to aid the control of post-TURP bleeding.
