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.

Ethanol monitoring of transurethral prostatic resection during inhaled anesthesia.

The purpose of this study was to examine the precision of a method of breath-alcohol analysis used to monitor absorption of irrigating fluid during transurethral resection of the prostate performed under inhaled anesthesia. A breath-alcohol analyzer (Alcolmeter SD-2) was placed between the endotracheal tube and the Bains' circuit. The concentration of ethanol in the breath, serum sodium concentration, and volumetric fluid balance were measured at 10-min intervals during 38 operations when the irrigating fluid contained 1.5% glycine and 1% ethanol. Ethanol monitoring detected absorption rates that exceeded 14 +/- 8 mL/min (mean +/- SD). In 17 patients in whom hyponatremia developed immediately in connection with absorption, the volume of irrigating fluid absorbed (up to 1950 mL) could be predicted from a single expired-breath test with a standard error of 325 mL. When the alcohol measurements were corrected for absorption time, the standard error was 215 mL. Seven other patients received 2.2% wt/vol glycine as irrigating fluid, and ethanol (0.35 g/kg) was administered by intravenous infusion. The direct and indirect measurements of the blood-alcohol concentration agreed well. These results confirm that ethanol monitoring is a viable technique during inhaled anesthesia for transurethral resection of the prostate.

[Balloon dilatation vs. prostatic transurethral resection in stages I-II prostatic adenoma].

Thirty consecutive patients with benign prostatic hypertrophy St. I-II (adenom weight < 25g) were treated either by balloon dilatation (Group I) or transurethral resection (group II). Peak flow, residual urine and voided urine did not improve after balloon dilatation in a follow-up of 9 months. In contrast peak flow enhanced after TUR-P from 10.4 ml/sec. to 21.9 ml/sec. Residual urine reduced from 65 ml to 30. In group I obstructive symptom score (6.1 > 4.5) and irritative symptom score (5.5 > 3.6) decreased after 9 months, TUR-P resulted in a greater reduction of obstructive score (7.4 > 1.6) and irritative score (6.0 > 2.4). This study with selected patients does not support indications for balloon dilatation.

ECG and cardiac enzymes after glycine absorption in transurethral prostatic resection.

The electrocardiogram (ECG) was recorded and the serum levels of creatine kinase (CK), aspartate transaminase (ASAT) and prostatic acid phosphatase (PAP) was measured in 22 patients undergoing transurethral resection of the prostate (TURP) under spinal or epidural anaesthesia. The irrigating fluid consisted of 1.5% glycine and 1% ethanol, and absorption of the fluid was monitored by detection of alcohol in the expired breath. The results show that nine of the 11 patients (82%) who absorbed more than 1,000 ml of irrigating fluid had developed ECG changes 24 h after the operations. The most common alteration was depression of the T wave. This sign was only seen in one (9%) of the patients who absorbed none or very small amounts of irrigating fluid (P < 0.001). The serum activity of CK and ASAT increased in five patients who also developed ECG changes, and the highest values were recorded 24 h after TURP. The CK-MB isoenzyme was detected in 85% of the samples with elevated total CK, but the criteria for myocardial infarction were never fulfilled. In contrast, PAP increased in all patients and the highest level occurred at the end of TURP. The activity-time profiles suggest that CK and ASAT entered the circulation by a mechanism different from that of PAP. We conclude that absorption of glycine solution during TURP is frequently followed by nonspecific ECG signs of altered cardiac function and also that the serum activities of CK and ASAT increase in some of these patients.

Radical retropubic prostatectomy after transurethral prostatic resection.

The 36 patients who underwent radical retropubic prostatectomy for adenocarcinoma after transurethral resection of the prostate were reviewed to evaluate the difficulty of the radical operation, the rate of morbidity and the survival. In 24 patients (67 per cent) the dissection proved to be routine; 18 patients (50 per cent) had perfect urinary control, whereas 4 were totally incontinent. There appears to be no untoward effect on survival, since all patients remain alive, 22 per cent having had followup for 5 years or more.

Venous air embolism during transurethral resection of the prostate.

Venous air embolism during transurethral surgery is a rare event. There have been case reports in the anesthesia and urology literature of fatal air embolism during transurethral prostate resection and transurethral incision of the bladder neck. We present a case of nonfatal venous air embolism during transurethral prostate resection in which incorrect assembly of the bladder irrigation-resectoscope-drain system led to a rapid entrainment of air into the open venous channels of the prostate bed.

Holmium laser resection of the prostate versus transurethral resection of the prostate: results of a randomized trial with 4-year minimum long-term followup.

PURPOSE: It has previously been shown that holmium laser resection of the prostate (HoLRP) is superior to transurethral resection of the prostate (TURP) with regard to perioperative morbidity and is equivalent to TURP in the short term. We present the long-term results of a randomized, prospective trial comparing HoLRP to TURP since information regarding the durability of holmium prostatectomy is lacking in the literature to date. MATERIALS AND METHODS: A total of 120 patients with urodynamic obstruction were randomized (April 1996 to August 1997) into 2 comparable groups and assigned to HoLRP or TURP. All patients were assessed preoperatively and followed prospectively at 3 weeks, 3, 6, 12, 24 and 48 months postoperatively with an American Urological Association symptom score, quality of life score, peak urinary flow rate, and questionnaires concerning sexual function and continence. Preoperative pressure flow studies, ultrasound prostatic volume assessment and post-void residual volume measurement were repeated at the 6-month visit. All adverse events were noted. RESULTS: Of 120 patients 73 completed the 48-month assessment. HoLRP and TURP resulted in significant improvements in all parameters. There was no difference between the 2 techniques in terms of urodynamic parameters, potency, continence and symptom scores at the 48-month assessment. HoLRP took significantly longer to perform but perioperative morbidity, catheter time, nursing contact time and hospital stay were significantly less for HoLRP compared to TURP. CONCLUSIONS: HoLRP and TURP give equivalent and satisfactory long-term results, with no differences noted in major morbidity. This confirms the durability of these 2 treatments. Peri-operative morbidity is less with HoLRP.

Species distribution and antibiotic sensitivity of bacteria isolated pre- and postoperatively from patients undergoing transurethral prostatic resection.

The identity and antibiotic sensitivity of the isolated bacteria from 179 patients undergoing transurethral resection of the prostate were analysed. The patients were randomized into a group receiving a short course of cefotaxime in conjunction with the operation and a control group given no antibiotics. Preoperatively 70 patients had bacteriuria (greater than or equal to 10(7) CFU/l) with a predominance of Gram-negative bacteria (57 isolates, mainly Escherichia coli, Enterobacter, Klebsiella ssp, Proteus ssp), although Gram-positive species (24 isolates, mainly enterococci and Staphylococcus epidermidis) were also frequently encountered. Preoperatively isolated pathogens were evenly distributed in both groups and the sensitivity pattern was comparable. In the cefotaxime group postoperative recurrence of the preoperatively identified bacteria occurred in a lower frequency (11/43) than persistence in the control group (24/38). Only Gram-negative pathogens were isolated from patients with postoperative septicemia and upper urinary tract infections indicating that it is most important to direct prophylaxis against Gram-negative bacteria. A high degree of sensitivity against cefotaxime, gentamicin, trimethoprim, co-trimazine and a combination of ampicillin and mecillinam was recorded among both pre- and postoperatively isolated bacteria.

Antibiotic prophylaxis for transurethral prostatic resection in men with preoperative urine containing less than 100,000 bacteria per ml: a systematic review.

PURPOSE: We determined whether antibiotic prophylaxis can reduce the risk of postoperative infective complications in men undergoing transurethral resection of the prostate (TURP) who have preoperative urine with less than 100,000 bacteria per ml. MATERIALS AND METHODS: MEDLINE, EMBASE (Elsevier B.V., Amsterdam, The Netherlands) and the Cochrane Library were searched for randomized and quasi-randomized controlled trials that compared the effects of antibiotic prophylaxis with placebo or active controls for men undergoing TURP with preoperative sterile urine. Two reviewers independently extracted patient characteristic and outcomes data based on a prospectively developed protocol. RESULTS: A total of 28 trials, 10 placebo controlled and 18 no treatment controlled, involving 4,694 patients, met the inclusion criteria. The mean age of the subjects was 69 years and the majority underwent TURP for prostatic hyperplasia (85%). Antibiotic prophylaxis was significantly more effective than placebo in reducing postoperative TURP complications. The risk differences for post-TURP bacteriuria, high degree fever, bacteremia and use of additional antibiotic treatment were -0.17 (95% CI 0.20, -0.15), -0.11 (-0.15, -0.06), -0.02 (-0.04, 0.00) and -0.20 (-0.28, -0.11), respectively. The results were observed consistently across all classes of antibiotics assessed. There was no difference in the duration of postoperative catheterization or hospitalization. Adverse events were rare, generally mild, and included allergic reactions, pyrexia and abdominal complaints. CONCLUSIONS: Prophylactic antibiotics decrease the incidence of post-TURP bacteriuria, high fever, bacteremia and additional antibiotic treatment. Additional research should evaluate the optimal antibiotic regimen, and whether the cost and possibility of the development of resistant strains of organisms justify the routine use of prophylactic antibiotics.

["Sand-clock" lithiasis on prostatic transurethral resection bed].

OBJECTIVES: Although uncommon, prostatic surgical bed lithiasis may present among post-TURP complications. The present study underscores the importance of diagnosis and treatment. METHODS/RESULTS: We report on a patient with magnesium ammonium phosphate hourglass lithiasis in the prostatic surgical bed one year and a half following transurethral resection due to adenomyomatous prostatic hyperplasia that was successfully treated by intracorporeal lithotripsy with the Lithoclast. The physiopathological, clinical, diagnostic and therapeutic aspects are discussed. CONCLUSIONS: This condition should be suspected in patients with dysuric syndrome post-TURP. The importance of simple complementary diagnostic procedures as DRE and plain abdominal films in discarding lithiasis in underscored. We consider retrograde endoscopic manipulation and ultrasonic lithotripsy or penumatic lithotripsy with the Lithoclast to be the safest procedures for this type of lithiasis.

Prophylactic chemotherapy with fosfomycin trometamol versus placebo during transurethral prostatic resection.

A prospective randomized controlled double-blind study was performed on 61 patients undergoing transurethral resection of the prostate. The first group of 31 patients received 3 g fosfomycin trometamol p.o. each on the evening before and after the operation; the second group of 30 patients received a placebo. Urine samples were taken by catheter puncture 24 and 48 h postoperative. After removal of the catheter (day 5) the first midstream urine was collected for culture, and from that moment on all patients were treated with a nitrofurantoin derivative for two weeks. Although the same strict antiseptic measures were standard practice for both groups, the incidence of early postoperative urinary tract infections was significantly lower for the fosfomycin trometamol group (0/31 versus 6/30 in placebo recipients). None of the patients suffered from a major symptomatic or complicated infection. There were no side effects registered.

[The significance of the characteristics of lubricating jellies in use during transurethral prostate resections with metallic sheaths (author's transl)].

If a metallic sheath is used during a transurethral resection of the prostate with high-frequency currents, the lubricating jelly has to exceed a prescribed conductivity, in order to prevent dangerous current-density spots within the urethra. Furthermore, the mechanical behaviour of the lubricating jelly and the mode of its application have to be considered carefully.

Transient blindness: unusual initial symptom of transurethral prostatic resection reaction.

Transient blindness was seen in 2 patients undergoing transurethral resection (TUR) of the prostate as the initial symptom of a severe TUR reaction. Cerebral edema of the occipital cortex is the most probable mechanism. Both fully recovered their vision when appropriately treated. Patients with visual disturbances during transurethral prostatectomy should be suspected of having a TUR reaction.
