Quality of life and treatment of hormone resistant metastatic prostatic cancer. The EORTC Genito-Urinary Group.

72 patients with hormone resistant, progressing prostatic cancer completed a self-administered questionnaire to assess subjective morbidity and quality of life before they were entered into a phase III trial of estramustine (34) vs. mitomycin (38). At least one post-treatment assessment was available in 43 patients. This considerable degree of non-compliance is explained by practical problems related to completion and collection of the questionnaires in these rapidly deteriorating patients. Doctors underestimated subjective morbidity (pain, decreased performance status, nausea) in 30-50% of the cases. Decreased functional status, fatigue and pain were identified as the most frequent major morbidities before study entry. In most patients, treatment did not reduce this morbidity. The routine application of self-administered quality of life questionnaires has considerable practical problems but yields clinically worthwhile information about subjective morbidity. Simple but relevant monitoring of subjective morbidity by the patient should be mandatory in cancer trials where palliation is a major endpoint.

Visual sexual stimulation plethysmography: complementary test to nocturnal penile plethysmography.

Diurnal penile plethysmography under visual sexual stimulation (VSS) and nocturnal penile tumescence (NPT) plethysmography have been performed in 5 healthy volunteers and 195 consecutive men complaining of impotence. Our study demonstrates that VSS plethysmography may compensate at least partially for the shortcomings of classic NPT plethysmography, by allowing direct clinical estimation of "erectile performance." Twenty percent of the patients had full erection under VSS. These patients do not need further testing. VSS is a noninvasive and useful "first-line" investigation in erectile dysfunction.

Renal rupture after transplantation.

Nine instances of spontaneous allograft rupture have been identified in a series of 325 renal transplantations. Repair of the graft was accomplished in 4 cases. One graft functioned for five and one-half years, one kidney was removed immediately because of uncontrolled hemorrhage, and two grafts were subsequently removed because of rejection. Immediate nephrectomy was performed in 5 cases of irreversible rejection. The duration of ischemia and method of preservation appeared to have no etiologic importance. Evidence of severe acute rejection was present in all 9 cases. The recent increase in graft rupture parallels the increasing frequency of severe early acute rejection reactions.

Undetectable prostate-specific antigen in aging men.

Undetectable prostate-specific antigen was found in three aging men despite the absence of any prostatic surgery or exogenous hormonal deprivation. Clinical and elementary hormonal workup revealed the presence of secondary hypogonadism. This finding confirms the hormonal dependency of this prostatic marker and may, in some cases, explain the discrepancy between prostatic volume and the value of serum prostate-specific antigen.

Laparoscopic nephrolithotomy: the value of intracorporeal sonography and color Doppler.

Laparoscopic nephrolithotomy was used as an alternative to open surgery in a patient who had failed extracorporeal shock-wave lithotripsy and whose anteriorly located stone-bearing calix precluded percutaneous extraction. Endocavitary ultrasonography and color Doppler render the procedure safe and effective; localization of the stone, selection of an optimal nephrotomy site away from large vessels and where cortical thickness is minimal, and control of fragment clearance are greatly facilitated.

Reversible renal artery stenosis in renal transplantation.

Spontaneous regression of an arterial stenosis in a renal transplant recipient is documented. Implications of this observation and possible pathogenic mechanisms are discussed.

Mycotic aneurysm of renal graft artery: diagnosis by ultrasonography.

Mycotic aneurysm of the renal graft artery is rarely detected before its rupture. Diagnosis up to now relied on arteriography. We report on a patient whose preoperative diagnosis was made by ultrasonography. Recent progress with this noninvasive procedure should allow earlier recognition of this life-threatening complication.

Free to total prostate-specific antigen (PSA) ratio improves the discrimination between prostate cancer and benign prostatic hyperplasia (BPH) in the diagnostic gray zone of 1.8 to 10 ng/mL total PSA.

OBJECTIVES: Improved discrimination between prostate cancer (PC) and benign prostatic hyperplasia (BPH) is clearly needed. Our aim in this study was to evaluate whether the free to total prostate-specific antigen (PSA) ratio would be useful in the gray zone of 1.8-10 ng/mL total PSA range. METHODS: In a consecutive series of 435 clinic patients referred for prostate evaluation, 308 had a total PSA < 10 ng/mL (92 had PC and 216 BPH). Free and total PSA were measured, and the free to total PSA ratio calculated. RESULTS: Total PSA values were significantly different between the two groups. For the 200 patients with a total PSA < 6 ng/mL, no significant difference in total PSA values were seen (P = 0.411), whereas free to total PSA ratios remained statistically different (P < 0.001). Receiver operating characteristic (ROC) curve analysis comparing the performances of total PSA over the ratio of free to total PSA showed a clear advantage for the ratio at all sensitivity levels. CONCLUSIONS: These data demonstrate that in a significant number (n = 308) of prostatic patients in the diagnostic gray zone of 1.8-10 ng/mL total PSA, the routine use of free to total PSA might be advantageous in discriminating between cancer and benign hyperplasia. This advantage remained for total PSA < 4 ng/mL. Further study is warranted to confirm these findings in an unselected population.

Early adjuvant adriamycin in superficial bladder carcinoma.

A multicenter study was performed in 110 patients with superficial transitional cell carcinoma of the bladder. Adriamycin (50 mg/50 ml) was administered intravesically within 24 h after transurethral resection of TA-T1 (O-A) bladder tumors. Instillation was repeated twice during the first week, then weekly during the first month and afterwards monthly for 1 year. The tolerance was evaluated in these 110 patients, and 29 patients presented with local side-effects. In 24 of these patients chemical cystitis was severe enough for them to drop out of the study. No systemic side-effects were observed. Recurrence was studied in 82 evaluable patients after 1 year of follow-up and in 72 patients followed for 2-3 years (mean 32 months). Of the 82 patients studied after 1 year, 23 had primary and 59 recurrent disease. Of the 82 evaluable patients, 50 did not show any recurrence after 1 year (61%), while 32 presented with one or more recurrences (39%). Of these recurrences, 27 were T1 tumors while five progressed to more highly invasive lesions. In patients that were free of recurrence during the first year, 80% remained tumor-free during the 2- to 3-year follow-up period. Of the patients developing one or more recurrences during the first year, only 50% presented with further recurrence once the instillations were stopped. The beneficial effect of Adriamycin appears obvious and might be related to the drug itself, the early and repeated instillations after TUR, or both.

Endopyelotomy. Prognostic factors and patient selection.

Although clearly a valid alternative to dismembered pyeloplasty for ureteropelvic junction obstruction in adults, endo(uretero)pyelotomy has not been universally accepted in the general urologic community because of the 10% to 30% inferior success rate and the concern regarding hemorrhagic complications. Identification of prognostic factors for success and complications are therefore of primary importance. The length of stricture, the grade of hydronephrosis, and the level of renal function are well recognized prognostic factors. Crossing vessels also play a role, and in association with the grade of hydronephrosis, they seem to be a major prognosticator of outcome. With attention to such prognostic factors, and appropriate patient selection, results can now approach the gold standard of dismembered pyeloplasty.

Efficacy of laser prostatectomy at 2-years' follow-up.

A total of 32 patients with symptomatic benign prostatic hyperplasia were treated with the right-angle firing neodymium:YAG laser fiber at a 60 W power setting. All these patients represented a high operative risk (ASA score > or = 3) and were excluded by the anesthesiologist for classic surgical treatment. Twenty-six patients were followed at least 24 months; the six remaining patients died of intercurrent disease. Efficacy of treatment was assessed at 3, 6, 12, 18, and 24 months postoperatively by International Prostatic Symptom Scores, peak urinary flow rates, prostatic volume, and radiographic or endoscopic imaging of the prostatic urethra. The mean preoperative symptom score was 25, the mean peak urinary flow rate 7.6 mL/sec, and mean prostatic volume 31 cc. At 2 years postoperatively, the mean symptom score was 5, the mean peak urinary flow rate was 19.3 mL/sec, and the mean prostatic volume was 18 cc. In two elderly patients, in spite of a significant improvement of symptomatology and peak flow rate, a surprisingly obstructed prostatic urethra was found endoscopically.

Transurethral ultrasound-guided laser-induced prostatectomy: a critical evaluation.

We evaluated 38 patients with a follow-up of 30 months after transurethral ultrasound-guided laser-induced prostatectomy (TULIP) for benign prostatic hyperplasia. The mean symptom score decreased by 54%, and peak urinary flow increased by 112%. For the entire series, 43.6% of the patients had an improved symptom score and 41% better urinary flow, but only 28.2% had improvement in both. Six patients (16%) required reoperation, two underwent a radical prostatectomy, and one patient presented total urinary incontinence. Also, 19% presented postoperative impotence, and 47% presented retrograde ejaculation. Although one third of the patients are improved with the TULIP procedure, the rate of complications is significantly higher than for TURP, which remains the most effective treatment of obstructive BPH.

Vessels around the ureteropelvic junction: significance and imaging by conventional radiology.

We studied the influence of vessels crossing the ureteropelvic junction and of the grade of hydronephrosis in 86 patients who underwent endoureteropyelotomy. With a follow-up ranging from 1 to 12 years, the presence of crossing vessels had a significant negative influence on the outcome and recurrence rate of the procedure. The success rate was 82% when no vessels were present but only 33% when crossing vessels were documented. In 13 of 15 failures (87%), a crossing vessel was found at open pyeloplasty. The degree of hydronephrosis was a less potent detrimental factor, with an 81% success rate in low-grade and 54% in high-grade hydronephrosis. The best results (90% success) were obtained in patients with no crossing vessels and low-grade hydronephrosis and the worst (30% success) in those with high-grade hydronephrosis in the presence of crossing vessels. Selection of patients according to those prognostic factors is recommended. Conventional intravenous urographic imaging techniques proved insufficient, and only angiography provided diagnostic accuracy; less-invasive methods are desirable.

[Non-surgical treatment of benign prostatic hypertrophy. Current status of the problem]. / Les traitements non chirurgicaux de l'hypertrophie bénigne de la prostate. Etat actuel de la question.

Benign prostatic hypertrophy is a highly prevalent disease, with a significant morbidity. Classical surgical therapy (open or transurethral adenomectomy) is very effective, but not without risks and complications. Better understanding of the pathogenesis of the disease have led to the development of several alternative treatments. Hormonal treatments are briefly reviewed, especially the preliminary results obtained with the 5-alpha-reductase inhibitors.

[The needlewoman crochet and the arterio-venous fistula of Cimino-Brescia (author's transl)]. / Le crochet de couturière et la fistule artério-veineuse de Cimino-Brescia

The authors describe a simple means of destroying the venous valves that oppose countercurrent perfusion of the distal venous segment of a latero-lateral arterio-venous fistula.

[Erratic course of bilateral renal angiomyolipomas]. / Evolution erratique d'angiomyolipomes rénaux bilatéraux.

We report a case of multiple and bilateral renal angiomyolipomas demonstrated and followed up by urography, sonography, and computed tomography during a period of 17 years. The diagnosis has been made by computed tomography. Follow-up examinations showed first a stability of the lesions, and afterwards, a rather fast increase of the volume of various masses, without symptoms, followed by a new period of stabilization.

[Contribution of the preoperative urodynamic findings in the determination of risks factors of urinary incontinence after radical retropubic prostatectomy]. / Apport de l'exploration urodynamique préopératoire dans la détermination des facteurs de risques de l'incontinence post-prostatectomie radicale totale.

UNLABELLED: The aim of the study was to determine whether preoperative urodynamic evaluation helps the physiotherapist to adapt preoperative management of patients undergoing radical retropubic prostatectomy (RP) by identifying a group at risk of incontinence. MATERIAL AND METHODS: We compared the preoperative urodynamic evaluation of 229 men scheduled for RP with their continence status, evaluated by standardized pad-test and questionnaire, at 6 weeks and 4 months postoperatively. RESULTS: The primary urinary incontinence risk has been obtained for five patient's categories, namely normal, bladder instability, bladder outlet obstruction, hypocontractility, and mixed results. None of the patients diagnosed with detrusor instability and bladder outlet obstruction was continent at six weeks from surgery. At four months, although it improves, the continence status remains significantly poorer than observed in all other groups. CONCLUSION: Preoperative urodynamic evaluation of patients scheduled for RP allows identifying patients with a high risk of postoperative urinary incontinence.

[Motor evoked potentials of the perineal floor. Preliminary results]. / Les potentiels évoqués moteurs du plancher périnéal. Résultats préliminaires.

Neuromotor pathways from the brain to the pelvic floor have been poorly documented. The recent development of Motor Evoked Potentials may well fill this gap in our basic knowledge. Our technique consists of transcutaneous stimulation of the motor cortex and sacral roots with a magnetic device while recording the evoked response from the bulbocavernosus muscle and anal sphincter. Cortical stimulation is performed first at rest and then during voluntary contraction of the examined muscles ("facilitation" procedure). Sacral root stimulation is performed at rest. Stimulation at 2 different levels allows measurement of the total transit time (brain to muscle transit time) and the peripheral transit time (sacral roots to muscle). By subtracting the latter from the former, the central transit time (brain to sacral roots) is obtained. The technique is painless, and to our knowledge no side effects have been reported. The authors present the preliminary results of this new technique.

[Ureteral lithiasis. Development of the therapeutic strategy and the place of endoscopic treatment]. / Lithiases urétérales. Evolution de la stratégie thérapeutique et place du traitement endoscopique.

In order to evaluate the impact of endourological techniques and extracorporeal lithotripsy on the management of ureteral calculi, we reviewed the charts of 838 patients requiring hospitalization for this pathology from 1982 till 1987. 314 patients were managed conservatively and 524 required intervention therapy: 52 with blind endoscopic techniques, 93 with open surgery, 122 with retrograde ureteroscopy, 168 with percutaneous extraction and 92 with ESWL. Evolution of the therapeutic strategy is discussed and our present approach to ureteral stone management is outlined.

[Retroperitoneal fibrosis due to barium]. / Fibrose rétropéritonéale sur baryte.

The authors report two cases of retroperitoneal fibrosis secondary to rectal perforation occurring during barium enema. In view of the variable interval between the radiological accident and the urological complications, a long patient follow-up is recommended. If ureteric obstruction occurs, ureteric catheterisation is a temporary alternative, but surgery is the treatment of choice. When ureterolysis cannot be performed, the authors propose ureteroileoplasty to restore continuity of the urinary tract.
