A randomized trial comparing holmium laser enucleation of the prostate with transurethral resection of the prostate for the treatment of bladder outlet obstruction secondary to benign prostatic hyperplasia in large glands (40 to 200 grams).

PURPOSE: Holmium laser enucleation of the prostate (HoLEP) is a surgical treatment for bladder outlet obstruction secondary to benign prostatic hyperplasia. HoLEP is a transurethral procedure that uses the holmium laser fiber (wavelength 2,140 nm) to dissect whole prostatic lobes off of the surgical capsule in retrograde fashion, while maintaining excellent hemostasis. The lobes are removed from the bladder by a purpose built transurethral morcellator, which means that large volume prostates can be enucleated endoscopically. We compared this procedure with transurethral prostate resection (TURP) in a randomized trial by evaluating outcomes in patients with a prostate volume of 40 to 200 ml on transrectal ultrasound. MATERIALS AND METHODS: A total of 61 patients with urodynamically proved bladder outlet obstruction secondary to benign prostatic hyperplasia were randomized to TURP or HoLEP. Perioperative parameters recorded included resectoscope, laser, electrocautery, morcellation and catheter time, hospital stay, bladder irrigation, volume blood transfusion the rate and resected tissue weight. Patients were followed 1, 3, 6 and 12 months postoperatively with peak urinary flow rate measurement and quality of life and American Urological Association symptom scores. Patients also underwent urodynamic assessment at 6 months with measurement of peak detrusor pressure at maximal flow, post-void residual volume and prostate volume by transrectal ultrasound. Continence, potency and all adverse events were recorded at each visit. RESULTS: HoLEP was superior to TURP in terms of mean catheter time (17.7 +/- 0.7 vs 44.9 +/- 10 hours) and hospital stay (27.6 +/- 2.7 vs 49.9 +/- 5.6 hours) but it required more time to perform (62.1 +/- 5.9 vs 33.1 +/- 3.7 minutes). More prostate tissue was removed in the HoLEP group (40.4 +/- 5.7 vs 24.7 +/- 3.4 gm). HoLEP was also superior to TURP in terms of relieving urodynamic obstruction at 6 months of followup (postoperative detrusor pressure at maximum flow 20.8 +/- 2.8 vs 40.7 +/- 2.7 cm H2O). HoLEP and TURP led to significant improvements in peak flow rates, symptom scores and quality of life scores compared with baseline and there was no significant difference between the 2 procedures with respect to these parameters at 12 months. Fewer adverse events were recorded in the HoLEP group. CONCLUSIONS: HoLEP is superior to TURP for relieving bladder outlet obstruction in men with benign prostatic hyperplasia. It allows more rapid catheter removal and hospital discharge. It requires more time to perform than TURP but more prostate tissue is removed, resulting in similar efficiency in tissue retrieval. HoLEP is equivalent to TURP in relieving men of lower urinary tract symptoms and in improving peak urinary flow rates at 12 months of followup.

[Sexual function after transurethral prostate resection].

The possible effects of transurethral resection of the prostate were investigated in a prospective trial. 46 patients who underwent surgery for benign prostatic hyperplasia were recruited. All patients had to have a sexual partner and had to be sexually active within 3 months prior to surgery. Sexual function was assessed with the Rust and Golombok Inventory of Sexual Satisfaction (GRISS). Statistical analysis of GRISS scores exhibited a significant decrease in the erectile capacity 6 months after surgery. However, only 2 men were impotent and unable to perform sexual intercourse. 41 men developed retrograde ejaculation which was reported to interfere with sexual satisfaction in 16 men and 9 of their female partners.

Transurethral prostatic resection in the treatment of prostatism with high urinary flow.

There were 51 patients with prostatism who were selected for transurethral resection of the prostate using clinical nonurodynamic criteria. Urodynamic evaluation revealed that 13 patients had preoperative maximum urine flow rates greater than 15 ml. per second. The favorable postoperative outcome in clinical and urodynamic terms in this group of patients with high preoperative urine flow is discussed.

Can the need for palliative transurethral prostatic resection in patients with advanced carcinoma of the prostate be predicted?

PURPOSE: To identify the factors predicting the need for palliative transurethral resection of the prostate (channel TURP) in patients with advanced carcinoma of the prostate (CAP) receiving androgen ablation therapy. PATIENTS AND METHODS: From January 1996 to January 2004, 203 patients with advanced CAP were treated by androgen ablation. Patients presenting with retention were catheterized initially, and those (N = 12) who failed a catheter-free trial and had immediate channel TURP were excluded. The remaining 191 patients were followed every 3 months (mean 35.5 months, range 6-92 months). Patients requiring channel TURP (group 1; N = 42 [22%]) during follow-up were compared with those who did not (group 2) for predictive factors, viz. retention of urine, serum prostate specific antigen (PSA) concentration, Gleason sum, prostate size, and bony metastasis at presentation. RESULTS: Channel TURP was performed at a mean of 21 months (range 3-72 months). The mean Gleason sum in this group was 7.88, whereas it was 7.29 in group 2 (P = 0.013). Retention at presentation was significantly more common in group 1 (N = 26; 61.9%) than in group 2 (N = 46; 30.8%; P = 0.001). Patients who did not present with retention and had Gleason sums < or =7 (N = 32) did not require channel TURP. Of the 14 patients who voided successfully after a catheter-free trial but had Gleason sums of >7, 71.4% required channel TURP. Other factors were not found to be significantly different in the two groups. CONCLUSION: High Gleason sum and retention at presentation are significant factors predictors of the need for channel TURP during follow-up in patients with advanced CAP receiving androgen ablation therapy.

Sexual function one year after transurethral prostatic resection. Patients' own assessments.

One year after transurethral resection of the prostate for benign hyperplasia, 127 men received a questionnaire requesting personal evaluation of sexual function, including erection, ejaculation, libido and satisfaction. Significant postoperative dysfunction was reported in all these respects: 54% of the responders claimed deterioration and half of them blamed the operation. Decline in sexual function had a multifactorial background, including advancing age, morbidity, and changed marital and social conditions. Although other examinations with preoperative and postoperative evaluation report a lower incidence of impotence development, which may be more reliable, it is psychologically interresting that the patients themselves suspect the transurethral resection as the cause of impaired sexuality.

[Complications and limitations of transurethral prostatic resection: retrospective study of 366 patients].

In present paper we report our experience on 366 patients underwent to transurethral resection of prostate from January 1988 to January 1990. All patients were controlled by uroflowmetry and retrograde plus minctional urethrography, with evaluation of the possible immediate and latest complications. Among the latest complications, the most representative had been urethral stricture, occurred in 24 patients (6.5%) according with international literature. We considered also various iatrogenics factors (operator experience, endoscopic time, catheter section, catheter permanence time, use of lubricator, presence of catheter before TURp, preventive Otis urethrotomy). From our study rises out that the most important risk factors are: a) catheter permanence time; b) TURp without preventive Otis urethrotomy.

[Questionnaire survey of peri-operative management of transurethral prostate resection in Japan].

OBJECTIVES: We investigated perioperative management for transurethral resection of the prostate (TURP) in Japan. METHODS: The questionnaire survey was conducted in 1,213 educational institutions for urology. RESULTS: The questionnaires were returned from 722 (60%) institutions. Admission to hospital was most frequently scheduled on preoperative day 1; termination of continuous drip infusion, starting meal intake and walking on postoperative day 1; intravenous antibiotics for three days; removal of Foley catheter on postoperative day 4; oral antibiotics for 7 days; and discharge from hospital on postoperative day 7. CONCLUSION: Although hospitalization was 14 days or less at most institutions, several procedures, especially the administration of prophylactic antibiotics, were fairly varied. Discussions from various perspectives might be needed to standardize the perioperative management of TURP in Japan.

Interstitial laser coagulation versus transurethral prostate resection for treating benign prostatic obstruction: a randomized trial with 2-year follow-up.

OBJECTIVES: To investigate whether interstitial laser coagulation (ILC) is as effective and as safe as transurethral resection of the prostate (TURP). The treatment of choice for bladder outflow obstruction secondary to benign prostatic hyperplasia is TURP. However, ILC is a less invasive outpatient procedure that may be as effective and safe as TURP. METHODS: In a multicenter randomized trial at six U.S. tertiary care hospitals, we treated 72 men with bladder outflow obstruction secondary to benign prostatic hyperplasia with either TURP (n = 35) or ILC (n = 37). The outcome measures were peak flow rate, postvoid residual urine volume, prostate volume, prostate-specific antigen levels, symptom and quality-of-life indexes, sexual function, and adverse event rates. Measurements were taken at baseline and at 3, 6, 12, and 24 months. RESULTS: At 2 years, the TURP patients had better median peak flow rates, but not significantly so (range 16.5 to 13.9 mL/s, 95% confidence interval for the 2.6 mL/s difference of -0.4 to 7.6). The median scores on the symptom indexes and quality-of-life measures were similarly improved in both groups. Of 37 ILC patients, 6 (16%) were retreated with TURP in the first year. Sexual function declined in the TURP group but remained stable in the ILC group. The adverse event rates were similar, although the events were more serious in the TURP group. CONCLUSIONS: ILC compares respectably with TURP. Given the advantages of an outpatient procedure, similar results in symptom reduction and quality-of-life measures, and less severe adverse effects, ILC can be an acceptable alternative to TURP.

Management of bladder stones: should transurethral prostatic resection be performed in combination with cystolitholapaxy?

We report our institutional experience and review the literature in the management of bladder stones, with particular attention to combined cystolitholapaxy and transurethral prostatectomy. Vesical calculi are associated with obstructing prostatic hypertrophy two thirds of the time. Combined cystolitholapaxy and transurethral resection of the prostate have significant morbidity.

[Transurethral prostatic resection with bipolar scalpel].

UNLABELLED: FUNDAMENTAL: [corrected] To show our initial experience in the TUR of prostate with bipolar axipolar bistoury. MATERIAL AND METHODS: Five patients with an average age of 72 years old, were operated between may and june 2002. They showed important increased in questionnaire symptoms (IPSS). The average ecographic volume has been 57.4 g. We employed Gyrus resector and physiological salt solution for continue irrigation. RESULTS: The average operative time was 70 minutes. None of the patients showed hyponatremia needed blood transfusion. In all the cases the sound was removed 48 hours after operation, one of them have urinary retention (UR) and need sound tow more days. Hospital stay was tree days except the patient how had UR. At 1 and 6 month there is improvement in the IPSS. CONCLUSIONS: TUR of prostate with bipolar axipolar bistoury can avoid the secondary effects of glicine and allows us to work with prostates of bigger volumes due to we have more time to do it. Nevertheless bigger and better studies are required to value the effectiveness of this new technology opposite the TUR of prostate with monopolar bistoury which keeps being the gold standard.

Comparison of forced-air warming and radiant heating during transurethral prostatic resection under spinal anaesthesia.

Forced-air warming is commonly used to warm patients intraoperatively, but may not achieve normothermia during a short procedure. Comparative trials of a new radiant warming device in general anaesthesia (Suntouch, Fisher and Paykel, Auckland, New Zealand) have had conflicting results. We conducted a randomized controlled trial to compare the efficacy and thermal comfort of the Suntouch radiant warmer and forced-air warming in patients at high risk of hypothermia during neuraxial blockade. With ethics committee approval, 60 patients having transurethral resection of the prostate under spinal were randomized to either radiant warming or forced-air warming. All intravenous and irrigation fluids were warmed but pre-warming was not used. The final intraoperative rectal temperatures for the radiant warming and forced-air warming groups were 36.1 degrees C and 36.4 degrees C respectively (P= 0.03). A large proportion of patients in both groups (46% and 33% respectively, P=0.3) were hypothermic (<36 degrees C) on arrival in the post-anaesthesia care unit. No other patient variables were significantly different. Neither warming device reliably prevented hypothermia, although forced-air warming was slightly superior.

[Prostate transurethral resection syndrome].

The "transurethral resection of prostate" syndrome (TURPS) is the clinical manifestation of the resorption into the patient's body of a large amount of glycocolle-containing irrigating fluid used for this procedure. The full clinical picture, which is seldom seen, consists of dyspnoea, nausea, arterial hypertension, an increased central venous pressure, cerebral oedema, cardiogenic shock and renal failure. Improved surgical techniques, as well as incomplete and atypical forms of the syndrome could explain this low incidence. Absorption into the blood stream may be rapid, by way of the prostatic venous plexi, or slower, from the spaces around the prostate and under the peritoneum. The present-day pathophysiological theory explains this syndrome by an acute hyponatraemia, sometimes dissociated from the hypoosmolality, the toxicity of glycocolle, and the neurological effects of hyperammonemia. Acute hyponatraemia, with blood sodium concentrations below 115 to 120 mmol.l-1, should be considered as potentially serious. The different mechanisms involved may act alone or together, thus explaining that the minor forms of the syndrome mostly consist of a neurological picture. The emergency treatment depends on the natraemia. It includes diuretics and progressive reloading of the patient with sodium in case of severe hyponatraemia with seizures. The best prevention is a correct surgical indication and technique. The resection should not last for more than 90 to 120 min. The major problem remains the early diagnosis of TURPS. Carrying out this surgery under regional anaesthesia is helpful for this purpose, but, in the near future, the best means might be the monitoring of expired ethanol concentrations.

Glycine solution as an irrigating agent during transurethral prostatic resection. Glycine concentrations in blood plasma.

In 17 men undergoing transurethral resection of the prostate (TURP), an isosmotic solution of 2.2% glycine was used for irrigation. The plasma glycine concentration was determined before and immediately after TURP and 2, 6, 24 and 48 hours later. The serum concentrations of sodium, albumin and prostatic acid phosphatase protein (PAP) were used as indicators of fluid absorption. Calculation of the absorbed fluid volume was based on the plasma concentration of glycine, and the disappearance rate of glycine from plasma was estimated. The mean disappearance rate (T 1/2) was 85 min, which was midway between previously observed rates for sorbitol and mannitol. The observed plasma glycine increase after TURP correlated well with fall in serum sodium and rise in serum PAP, with the blood loss during and up to 15 min after TURP, and also with the weight of the resected tissue. The plasma glycine level, highest immediately after TURP, normalized 24-48 hours postoperatively. No signs of ammonia intoxication or marked serum urea increase were seen in these patients, although some had very high plasma glycine values after TURP (mean 10.2, maximum 23 mmol/l) as compared with the preoperative levels (mean 0.2 mmol/l). There was some increase of plasma serine (a normal metabolite of glycine) after TURP. The authors conclude that the irrigating fluid should have a minimal concentration of glycine, near to the level of haemolysis onset, to minimize the plasma dilution effects, including hyponatraemia, and the appearance of metabolites when the irrigating fluid is absorbed.
