ABSTRACT

STUDY DESIGN: Retrospective study. OBJECTIVE: To examine the functional results and effect on quality of life of continent cutaneous urinary diversion in spinal cord injured patients. SETTING: Department of Urology, Sahlgrenska University Hospital, Göteborg, Sweden. SUBJECTS: A total of 10 patients with spinal cord injury (SCI). METHOD: The patients were operated on with an ileal reservoir (Kock reservoir or T-pouch), Cr-EDTA clearance was determined preoperatively and at follow-up. The patients answered a questionnaire concerning reservoir function, various activities and quality of life. The patient charts were reviewed. RESULTS: One patient died of pulmonary embolism 3 years after surgery. Two patients were reoperated on for reservoir perforation. All patients were satisfied/very satisfied with their reservoirs. Half of them reported improved ability to perform various activities. Eight out of nine patients reported improved quality of life. CONCLUSION: For a selected group of patients with SCI, continent cutaneous urinary diversion provides successful outcome with improved quality of life.

ABSTRACT

The aim of this study was to use a systematic schedule, including urodynamics, to describe the rate of coexisting overactive bladder (OB) in patients with bladder outlet obstruction (BOO) caused by benign prostatic hyperplasia (BPH). We also identified differences between the patients with pure BOO compared with those with BOO combined with OB (BOO + OB). One hundred and sixty-two men referred to our clinic due to LUTS were included. Patients with a history that might affect their bladder function were excluded. After cystometry and pressure-flow studies, the patients were divided into pure BOO and BOO + OB. Of the 162 men, 55% had pure BOO. BOO + OB was found in 45%. Age, s-PSA, voided volume, and obstruction grade differed significantly between the groups. The patients with BOO + OB were older, had a higher s-PSA, voided smaller volumes, and were more obstructed. We found no differences in TRUS-volume, Q-max, IPS score, or PVR. There was a strong association between OB and BOO, the percentage of OB increasing with increased obstruction. TRUS-volume, Q-max, IPS score, and PVR did not predict whether the patients had a combined BOO + OB or not. These findings indicate that BOO is a progressive disease, which in time causes pronounced obstruction and perhaps in itself contributes to the development of OB.

ABSTRACT

OBJECTIVE: To report an integrated analysis of two previous studies fully characterizing the clinical utility of the controlled-release gastrointestinal therapeutic system (GITS) formulation of doxazosin in the treatment of benign prostatic hyperplasia (BPH). PATIENTS AND METHODS: Two pivotal randomized, double-blind studies of doxazosin GITS for BPH were assessed by an integrated analysis. Both studies included a 2-week washout period, a 2-week single-blind placebo run-in phase, and a 13-week double-blind treatment phase. One study compared doxazosin GITS, doxazosin standard (-S) and placebo in 795 men; the other compared doxazosin GITS and doxazosin-S in 680 men. Doxazosin GITS was initiated at 4 mg once daily and titrated to 8 mg once daily after 7 weeks, and doxazosin-S was initiated at 1 mg once daily and titrated to a maximum of 8 mg once daily over 7 weeks as needed to achieve optimal symptom control. The primary outcome measures were mean changes from baseline to the final visit for the International Prostate Symptom Score (IPSS) and maximum urinary flow rate (Qmax) in the per-protocol population. Numerous symptom- and urinary-related secondary outcomes were assessed, as were effects of therapy on male erectile dysfunction measured using the International Index of Erectile Function (IIEF) in one study. RESULTS: Both doxazosin GITS and doxazosin-S significantly improved the symptoms of BPH, as shown by a 45% reduction for each in total IPSS from baseline to final visit, compared with a 34% reduction in patients on placebo. Doxazosin GITS and doxazosin-S produced comparable improvements in Qmax that were significantly greater than with placebo, with a greater improvement sooner after treatment with doxazosin GITS than with doxazosin-S. Nearly half of the patients on doxazosin GITS had symptom relief at the 4-mg starting dose. A similar number of patients in both doxazosin groups were titrated to the maximum dose. Secondary outcomes were consistent with the primary effects. Both doxazosin GITS and doxazosin-S produced significant improvements in sexual function according to IIEF scores among those with dysfunction at baseline. The overall incidence of adverse events was similar among patients treated with doxazosin GITS and placebo, and slightly lower than those on doxazosin-S. There was no apparent difference in the type of adverse events reported for the two formulations of doxazosin, although most adverse events were reported at a lower frequency with doxazosin GITS. CONCLUSION: Doxazosin GITS is significantly more effective than placebo in reducing the clinical symptoms of BPH and improving Qmax, and as effective as doxazosin-S. Both doxazosin formulations improved sexual function in patients with BPH and sexual dysfunction at baseline. Doxazosin GITS produced a therapeutic effect equivalent to that of doxazosin-S, but with fewer titration steps and a slightly lower overall incidence of adverse events.

ABSTRACT

OBJECTIVE: An essential part of investigation of the lower urinary tract is pressure/flow studies (pQS). In fact, pQS is the only way of diagnosing bladder outlet obstruction. There is controversy regarding whether or not prophylactic antibiotic treatment is necessary. This prospective study was carried out in order to determine the frequency of infections and/or distress after pQS performed without the use of antibiotic prophylaxis. MATERIAL AND METHODS: One hundred and twenty-three patients were included in the present study, all males. They were requested to answer a questionnaire I week after pQS. Questions were asked concerning symptoms of voiding disorders, dysuria, hematuria, incidence of fever and the patient's acceptance of the investigation after the pQS procedure. Urine was obtained for culture immediately before the investigation and 3 and 7 days after the pQS. RESULTS: Forty-six per cent of the patients experienced some degree of transient dysuria after pQS. and 18.5% experienced voiding problems of varying nature. Five per cent of the patients had hematuria and 2.5% reported fever. Fifty per cent of the patients experienced some degree of discomfort during the pQS investigation, and 4.1% had positive culture and symptoms of UTI requiring antibiotic treatment. CONCLUSIONS: PQS is well accepted by the patients and the regular use of propylactic antibiotics is not indicated. We recommend, though, that patients at risk for serious complications from infections (e.g. those with prosthetic heart valves) should receive prophylactic antibiotics.

ABSTRACT

OBJECTIVE: One of the most common "treatment" alternatives in suspected outflow obstruction due to bladder outlet obstruction (BOO) is watchful waiting (WW). The aim of this study was to see whether there were any differences in outcome between patients with slight, moderate or severe obstruction due to BOO as classified by transrectal ultrasound (TRUS) and urodynamics. MATERIAL AND METHODS: Thirty-seven men with lower urinary tract symptoms (LUTS) and suspected BOO were included. All of the patients were investigated by a routine investigation schedule, including TRUS and urodynamics with pressure-flow measurement (pQS) at baseline. Patients with cancer in the urinary tract, prostatitis, history of detrusor hyperreflexia (peripheral or central diseases or trauma to the nervous system affecting the bladder) and serious systemic diseases were excluded. Patients were examined at baseline, then checked again after 1 year and 4 years. Patients who did not want to continue with WW were listed as treatment failures. RESULTS: At baseline, 43.2% of the patients were urodynamically severely obstructed and 32.3% were moderately obstructed. Thirty-five per cent of the patients were found to have previously unknown detrusor hyperactivity/overactivity. The prevalence of detrusor hyperactivity/overactivity increased with BOO. After 1 year, IPSS had decreased at unchanged Qmax and postresidual volume. These findings persisted at 4 years. The failure rate increased in the more obstructed patients and was significantly higher with more severe obstruction. Complications were found in 13.5%, with no significant differences between patients with minor BOO [Detrusor Adjusted Mean PURR Factor (DAMPF) scale <42], moderate BOO (DAMPF 42-65) and severe BOO (DAMPF >65). CONCLUSIONS: In patients with severe BOO, the LUTS and failure rate increase over time. The percentage of patients with detrusor hyperactivity/overactivity was higher in the severely obstructed group. By including full urodynamics when investigating patients with BOO, it seems possible to predict the failure rate according to the patients' obstruction grade. This gives an opportunity to treat the patient with minimal invasion, and to give the individual patient a more precise prognosis if WW is preferred.

ABSTRACT

OBJECTIVE: Many different treatments for lower urinary tract symptoms (LUTS) due to bladder outlet obstruction (BOO) are available today. To select the most suitable method for each patient is therefore a delicate task. The aim of this study has been to use a standardised systematic investigation schedule including pressure flow studies (pQS) in order to try to use graded treatment according to obstruction. METHODS: Ninety-nine patients were systematically examined with routine investigations and pQS to select between 3 treatment options, TURP, TUMT 2.0 (low energy) and watchful waiting (WW). Patients with severe BOO were recommended TURP, patients with moderate BOO were treated with TUMT and patients with no or minor BOO were recommended WW. RESULTS: TURP produced the best improvement in maximum free flow (Q-max), IPS-score and PVR, but only TURP had serious complications. TUMT treatment produced a more moderate improvement in flow rate, IPS-score and PVR, and all of the complications were minor. WW did not improve PVR or Q-max but the IPS-score decreased significantly. One UTI was the only complication in the WW group. CONCLUSIONS: pQS can be used to allocate patients with LUTS due to suspected BOO into different treatment arms; TURP, TUMT, WW, all with known different effects of BOO and with different severity of complications. Good symptomatic effect in Q-max, PVR and IPS-score with less serious complications and at low failure rate can thereby be obtained.

ABSTRACT

To assess the durability of the results of transurethral microwave thermotherapy (TUMT) for symptomatic benign prostatic hyperplasia (BPH), we have reviewed publications describing trials with at least 3 years of follow-up. For men treated only by TUMT, improvement in symptoms and quality of life appears to be maintained for at least 4 to 5 years. Improvement in peak flow rates is modest but is generally maintained, particularly after higher-energy therapies. These results represent responders, and a crucial question is the need for additional treatments. With lower-energy treatment, this is common: between 50% and 60% within 3 to 5 years. With higher-energy TUMT, the retreatment rate appears to be less, approximating 20% within 3 to 4 years. When comparing these results with those of transurethral resection, it should be noted that there is a significant failure rate with surgery, and even if failure is more common with TUMT, men may be prepared to accept this risk rather than the greater morbidity of prostatectomy.

ABSTRACT

BACKGROUND: The alpha(1)-blocker doxazosin mesylate is an established efficacious and welltolerated treatment for benign prostatic hyperplasia (PBH). However, its clinical utility can be limited by the need for multiple titration steps, starting at an initial dose of 1 mg, increased up to 8 mg once daily, to achieve optimal therapeutic response. A new controlled-release gastrointestinal therapeutic system (GITS) formulation of doxazosin mesylate enhances the pharmacokinetic profile and drug delivery rate, reducing the plasma doxazosin mesylate peak-to-trough ratio and minimizing the need for titration. OBJECTIVE: A study was conducted to assess the effects of doxazosin GITS 4 or 8 mg once daily, doxazosin standard 1 mg to 8 mg once daily, and placebo, in 795 men with BPH. This randomized, double-blind, multicenter Scandinavian study included a 2-week washout period, 2-week single-blind placebo run-in phase, and 13-week double-blind treatment phase. Doxazosin GITS was initiated at 4 mg once daily and titrated to 8 mg once daily after 7 weeks, if indicated, and doxazosin standard was initiated at 1 mg once daily, titrated to 2 mg after 1 week, to 4 mg at 3 weeks, and to 8 mg at 7 weeks if indicated, to achieve symptom control. The primary outcome measures were mean changes from baseline to the final visit for International Prostate Symptom Score (I-PSS) and maximum urinary flow rate adjusted for baseline values. RESULTS: Both doxazosin GITS and doxazosin standard significantly improved the symptoms of BPH, as evidenced by least-squares mean reductions in total I-PSS of -8.0+/-0.3 and -8.4+/-0.3 from baseline, respectively, compared with a reduction of -6.0+/-0.4 in patients on placebo. Doxazosin GITS and doxazosin standard produced clinically comparable improvements in maximum urinary flow rates, with a greater improvement observed earlier following treatment with doxazosin GITS than with doxazosin standard. Both active treatments produced significantly greater increases in maximum urinary flow rate compared with placebo. Nearly half of the patients on doxazosin GITS achieved symptom relief at the 4-mg starting dose. A similar number of patients in both doxazosin groups were titrated to the maximum dose of 8 mg for both formulations. The overall incidence of adverse events was similar among patients treated with doxazosin GITS and placebo, and slightly higher in those on doxazosin standard. There was no apparent difference in the type of adverse events reported for the two formulations of doxazosin, although most adverse events were reported at a lower frequency with doxazosin GITS. CONCLUSIONS: Doxazosin GITS is significantly more effective than placebo in reducing the clinical symptoms of BPH and improving maximum urinary flow rate, and as effective as doxazosin standard. A therapeutic effect equivalent to that of doxazosin standard was achieved with doxazosin GITS with fewer titration steps, in a manner that appeared to be better tolerated. Because treatment with doxazosin GITS starts with an effective dose for many patients, it is likely that this clinical profile will result in the need for fewer patient visits than with doxazosin standard therapy.

ABSTRACT

To study home uroflowmetry and to compare this method to free or "traditional" uroflowmetry in the evaluation of the patient with symptomatic benign prostatic hyperplasia (BPH), and the relationship between the values of home uroflowmetry parameters and bladder outlet obstruction (BOO). Twenty-five patients (mean age, 67 years) with symptomatic BPH were examined with home uroflowmetry, free uroflowmetry, and pressure-flow measurement. The patients were assessed using the International Prostate Symptom score; digital rectal examination; routine blood chemistry, including serum prostate-specific antigen level; urinanalysis; transrectal ultrasonography; and post-void residual urine. The 24 hr were divided into "active time" (AT) and "sleep time" (ST). AT home uroflowmetry parameters were compared to ST ones. The home uroflowmetry parameters were compared to respective ones of the free uroflowmetry as well and those obtained by pressure-flow measurement. The patients were asked about their opinion of home uroflowmetry. Home uroflowmetry was found to be a simpler and more acceptable method than free uroflowmetry. The mean Qmax of AT was significantly greater than the mean Qmax of ST, but the mean voided volume and mean voiding time of ST were significantly larger than those of AT. There was a close relationship between the mean Qmax at home and the Qmax in hospital, but the voided volume and voiding time measured in hospital were significantly larger than those at home. Home uroflowmetry provided an estimation of BOO for 46% of the patients as low if the home mean Qmax was >14 ml/sec, and as high if the home mean Qmax was <10 ml/sec. Home uroflowmetry was well accepted by the patients and gave more information than free uroflowmetry. In 46% of the cases, an estimation of BOO was obtained with home uroflowmetry.

ABSTRACT

OBJECTIVE: To compare costs of transurethral prostatic resection (TURP) and transurethral microwave thermotherapy (TUMT) for symptomatic benign prostatic hyperplasia (BPH) in a randomized, controlled trial. METHODS: In 70 BPH patients all costs were calculated for management, including complications and repeat treatment, during TURP or TUMT and 24-month follow-up. Clinical outcome was judged from Madsen-Iversen symptom score, peak urinary flow and residual urine. The effect of changes in some critical variables was assessed by sensitivity analysis. A cost-effectiveness analysis was carried out to compare the two methods. RESULTS: Symptom reduction after 2 years was 92% in the TURP group and 83% in the TUMT group. The total costs over 2 years were SEK 24,234 and 14,830 in the respective groups. Costs for retreatments were higher after TUMT, while complication costs were higher in the TURP group. TUMT costs depend on the investment for the equipment, including disposable probes, and the degree of its utilization. TUMT was more cost-effective than TURP in relieving BPH-related symptoms during the 2-year follow-up. CONCLUSIONS: Primary treatment costs were lower for TUMT than for TURP. Complication costs were higher in the trial's TURP arm, while retreatment costs were greater in the TUMT arm. TUMT costs depend on investment in and utilization of the equipment and reuse of treatment probes. TUMT was more cost-effective than TURP in the 2-year study period.

ABSTRACT

OBJECTIVE: To identify clinical variables useful in predicting outcome after transurethral microwave thermotherapy (TUMT) of the prostate with Prostasoft v. 2.0. PATIENTS AND METHODS: Thirty-eight men with symptomatic benign prostatic hyperplasia (BPH) were treated with TUMT using the Prostatron device with the low-energy (v. 2.0) software. Before and 6 months after treatment symptoms were evaluated using the Madsen-Iversen (M-I) symptom score, a clinical examination and suprapubic pressure-flow measurement, free urinary peak flow rate (Qmax) and determination of post-void residual urine volume (PVR). Bladder outlet obstruction was assessed from urodynamic pressure-flow studies using the classification of Abrams and Griffiths, the obstruction grading of Schäfer, and calculation of other published factors, e.g. the urethral resistance, an obstruction index and the detrusor adjusted mean passive urethral resistance factor (DAMPF). Categories of M-I score (total, irritative and obstructive), PVR and Qmax were investigated to determine whether any could predict the outcome after low-energy TUMT. The values after treatment and changes in Qmax, M-I score and PVR were used as efficacy variables. RESULTS: Variables describing infravesical obstruction had predictive characteristics that may be useful in selecting patients for TUMT v. 2.0 and significantly better results were obtained in patients with a low to moderate obstruction as graded using the DAMPF classification of obstruction. The results also indicated that patients with a high irritative M-I score or a Qmax of 7-14 mL/s were those who fared best after TUMT. CONCLUSIONS: Variables expressing the obstruction grade seem to be useful in predicting outcome after TUMT (v. 2.0). Patients with a high obstruction index are probably unsuitable for TUMT (v. 2.0).

ABSTRACT

The objective of this study was to assess the use of temporary stenting of the prostatic urethra for the prevention of acute urinary retention after high-energy transurethral microwave thermotherapy (TUMT) of the prostate. Stenting was performed immediately after high-energy microwave therapy. Two stents were used at two sites; at one site a silicone transurethral prostatic bridge was used in 42 patients, and at the second site a self-reinforced polyglycolic acid (SR-PGA) biodegradable spiral was used in 16 patients. Patients were scheduled for TUMT for symptomatic benign prostatic hyperplasia. Preoperative investigations included determination of a symptom score, measurement of the peak flow rate, and determination of the voided volume. The patients were treated using the Prostatron TUMT system. The software used provided a maximal power output of 70 W. After 1 week as well as 1, 3, 6, and 12 months the measurements were repeated and the effect of the stents was assessed. The symptom score, peak flow rate, and voided volume showed a significant improvement. Improvement was observed at first visit and sustained during the follow-up. Prophylaxis of acute urinary retention after TUMT can easily be managed by temporary stenting of the prostatic urethra. Temporary stenting can be routinely proposed after high-energy TUMT of the prostate.

ABSTRACT

OBJECTIVE: To assess the use of high-energy transurethral microwave thermotherapy (TUMT) for large severely obstructing benign prostatic hyperplasia (BPH) and to compare the use of a biodegradable stent with that of a urethral Foley catheter after TUMT. PATIENTS AND METHODS: The study comprised 30 men (mean age 71 years, range 49-82) scheduled for prostatectomy for symptomatic BPH. Pre-operative investigations included the measurement of urinary free flow rate, residual urine volume (ultrasonographically), a digital rectal examination, transrectal ultrasonography, a symptom score, cystoscopy, cystometry and pressure-flow. The obstruction was graded according to the Schäfer nomogram. The patients were treated using the Prostatron (EDAP-Technorned, France) TUMT system; the software used provided a maximum power of 70 W. Patients were catheterised after treatment with either a Foley catheter or a biodegradable stent. After 3 months, the measurements and obstruction grading were repeated, and the effect of the stent assessed. RESULTS: In the entire group, the mean (SD) free flow increased from 7.7 (2.4) to 14.0 (3.3) mL/s, the residual urine decreased from 125 (86) to 23 (25) mL and the symptom score decreased from 16 (8) to 5 (4). The mean (SD) degree of obstruction decreased from 81.0 (16) to 62.6 (15). The biodegradable stent completely avoided post-treatment retention. CONCLUSION: High-energy TUMT can be used on large severely obstructing prostates with major subjective and objective improvements. The biodegradable stent is useful in relieving the problems of catheterization after treatment.

ABSTRACT

This study includes 15 men between 48 and 81 years of age with treatment-requiring symptomatic benign prostatic hyperplasia (BPH). No patient with a urinary infection or prostate cancer was included. The serum concentrations of prostate-specific antigen (PSA), total as well as "free", i.e. noncomplex bound, were repeatedly determined before and up to 3 months after transurethral microwave thermotherapy (TUMT) of the prostate. After TUMT we found significant rises of the ratios of the serum total PSA concentration/prostate volume (up to 55-fold, mean 13.1) and of the serum free PSA concentration/ prostate volume (up to 26-fold, mean 10.2). The highest values for the serum total PSA concentration/prostate volume ratio were found on the first day after TUMT. Maximal serum free PSA concentration/prostate volume ratio occurred 3-6 h after treatment. The serum concentration/prostate volume ratios for total and free PSA returned to normal within 3 months. The results indicate that PSA determinations might be used as effect indicators of TUMT.

ABSTRACT

In this study we have investigated 70 men fulfilling the usual criteria accepted for transurethral resection of the prostate (TURP). The anamnestic evaluation included the Madsen-Iversen symptom score and a quality of life questionnaire. The clinical examination included suprapubic pressure flow measurement, free urinary flow, the determination of residual urine and the ultrasound evaluation of the size of the prostate. The clinical data were correlated with the grade of obstruction according to Schäfer calculated from the pressure/flow studies. No correlation was found between the grade of obstruction and anamnestic symptom data, the size of the prostate or residual urine. A slight correlation was found between the Schäfer grade of obstruction and the flow curve pattern or peak flow.

ABSTRACT

OBJECTIVE: To compare the outcome of transurethral resection of the prostate (TURP) and transurethral microwave thermotherapy (TUMT) on symptomatic benign prostatic hyperplasia (BPH). PATIENTS AND METHODS: Patients with symptomatic BPH were treated by either TURP (32 patients; mean age 70 +/- 6 years) or TUMT (37 patients; mean age 67 +/- 9 years) and assessed using the Madsen-Iversen symptom score, measurements of urinary free flow rate and post-void residual urine volume, digital rectal examination, transrectal ultrasonography, cystometry and pressure-flow measurement, ultrasonography or intravenous pyelography (IVP) of the upper urinary tract, urine analysis and routine blood chemistry including serum prostate-specific antigen (PSA) level. Examinations were repeated at fixed intervals for up to 24 months after treatment. RESULTS: After both TURP and TUMT there was an improvement in symptom score, residual urine volume, free flow rate and infravesical obstruction. The improvements of free flow rate and obstruction were more pronounced after TURP. Serious complications, such as bleeding requiring a re-operation, occurred only in patients who underwent TURP. CONCLUSION: Satisfactory results were obtained after both treatments and the improvements with either treatment lasted for at least 24 months.

ABSTRACT

The preferable operation for varicocele is ligation of all venous trunks of the spermatic vein above the internal orifice of the inguinal canal, traditionally performed by a retroperitoneal approach. An alternative method is laparoscopic ligature of the spermatic veins. To evaluate this procedure and to see if it can be done on an outpatient basis, 24 patients were operated upon laparoscopically. The patients were allocated to two series, one scheduled to be operated upon on an outpatient basis and one hospitalised. In 22 out of 24 patients the varicocele had disappeared completely at follow-up 1-3 months after the operation. Three of the patients operated upon late during the day in the outpatient group had to stay overnight. No complications occurred. The costs were more than 50% lower in the outpatient group. Laparoscopic ligature of the spermatic veins seems to be an attractive way to treat varicoceles, with good postoperative results and, if performed on an outpatient basis, with a substantial reduction of costs.

ABSTRACT

The results of transurethral microwave thermotherapy (TUMT) were compared in a prospective randomized study with those of transurethral resection (TURP) in patients with benign prostatic obstruction. In this preliminary report, 39 and 40 patients treated with TUMT and TURP, respectively, were followed between 2 and 12 months. Statistically significant improvements in symptom score, maximum flow rate, residual urine and maximum bladder capacity at cystometry were observed in both groups. The improvements were more pronounced in the TURP group, but major complications were more frequent in this group. Results are compared to other published studies.
