Paraureteral extrusion of calculi after endoscopic pulsed-dye laser lithotripsy.

Laser lithotripsy has become an effective and low-morbidity procedure for the treatment of ureteral calculi. Nevertheless, ureteral endoscopy is not free of side effects and complications. Lithiasis extrusion is one of the early complications of this procedure, and usually, the diagnosis is carried out by means of urographic findings because it is not easily recognized during ureteroscopy. Between January 1990 and May 1996, a total of 1047 endoscopic lithotripsies with the pulsed-dye laser were performed in our department. The 3-month stone-free rate as a single treatment was 76.5%. We found 11 cases (1.05%) of calculi extrusion after ureteral endoscopic treatment. Only one case was diagnosed intraoperatively. The evolution after a mean follow-up period of 18 months (range 6-34 months) was satisfactory in all cases. No urinary extravasation, infection, or secondary ureteral strictures were found. According to the absence of side effects, it was considered unnecessary to remove the extruded calculi. Extrusion of noninfected calculi into the periureteral tissues after laser lithotripsy causes no significant consequences and can be successfully managed conservatively. Knowledge of this possible complication is the best way to avoid it. A careful technique and a low irrigant flow will be very helpful.

[Combined endoscopic treatment with extracorporeal lithotripsy in chronic calcifying pancreatitis].

In the management of severe chronic pancreatitis, a variety of new endoscopic methods have been proposed as an alternative to traditional surgery. The main goal of these procedures is the remission of pain. They include pancreatic endoscopic sphincterotomy with subsequent endoscopic extraction, which can be associated to extracorporeal shock-wave lithotripsy for stone desintegration before removal of large calculi, and to the insertion of a pancreatic stent in case of a pancreatic duct stricture. We present two cases of severe chronic pancreatitis managed successfully with this endoscopic treatment.

[Extracorporeal shockwave lithotripsy: an alternative treatment for lithiasis of caliceal diverticula].

Among all the patients treated in our Lithotrity Unit, 13 of them had lithiasis inside the calyceal diverticulum. They were all treated by extracorporeal shockwaves. In none of the cases complete expulsion of lithiasic mass was achieved. In 3 (23%) cases it was reduced to half. In 2 (15.3%), 75% of the initial mass remained; and in 8 (61.5%) stones were fragmented but none of their debris was eliminated. Out of all the patients who were symptomatic before starting treatment, only 36.6% become asymptomatic. Extracorporeal lithotrity is, therefore, an approach with limited results in the calyceal intradiverticular lithiasis.

[Abdominal echography to determine the weight of the prostate].

The relationship of post-operatively determined prostatic gland weight and that calculated prior the procedure, by means of abdominal ultrasound techniques using the "ellipsoid method", has been studied in 88 patients undergoing retropubic adenectomy. The regression line was nearly optimal, Y = 0.946 X + 2.295, and the correlation coefficient between both weight measures was r = 0.915. Abdominal ultrasound examinations are a simple, quick and safe means to evaluate prostate weight, prior to deciding the type of surgery (open adenectomy or transurethral resection) for prostate adenoma.

Urological complications associated to uterus didelphys with unilateral hematocolpos. A case report and review of the literature.

Complete duplication of vagina, cervix and uterus, with imperforate hemivagina and renal agenesis is a rare condition with less than 120 cases published. In those articles, urological complications are uncommon with only a 10% of the total. We report 2 cases of uterus didelphys with unilateral hematocolpos and ipsilateral renal agenesis with urological clinical complications. One of them presented a very rare onset complaining of acute urinary retention. The other patient was referred for difficulty in micturition and abdominal pain which is the most common symptom of this entity. A description of both cases and a literature review of this congenital complex syndrome and its urological complications are reported.

Agenesis of seminal vesicles in infertile males: ultrasonic diagnosis.

We present the incidence of seminal vesicle agenesis and its association with deferens ductus agenesis in 141 males presenting with infertility. Transrectal ultrasonography was performed in every patient. Ten presented seminal vesicle agenesis (8 unilateral and 2 bilateral). Three had absence of the vas deferens on physical examination (3 of 7 with unilateral seminal vesicle agenesis and 1 of 2 with bilateral). Computed tomography confirmed the ultrasound findings. We emphasize the importance of the anomalies as a cause of infertility and the association with other genitourinary anomalies. Moreover, we state the necessity of transrectal ultrasound in the diagnosis.

Renal cell carcinoma: late recurrence in 2 cases.

We present 2 patients with late recurrence 16 and 11 years after nephrectomy for renal cell carcinoma. Metastases were solitary and their location very uncommon (vastus externo muscle and colon). In the reviewed series of 5,758 patients with renal cell carcinoma only a temporal muscle metastasis and another in the colon were observed but none of them was solitary.

[Contribution of echography to the study of the andrologic patient].

Our experience in the ultrasonographic evaluation of the prostate and seminal vesicles in prostatitis and male infertility are reported herein. In our view, this noninvasive imaging technique must be performed before recurring to other methods that involve manipulation. Similarly, we discuss the possibilities of duplex Doppler in the diagnosis of vascular disorders in the male consulting for impotence. We believe this simple noninvasive imaging technique can significantly reduce the number of patients that may require cavernosometry and cavernosography.

[Volumetric and structural changes of prostatic carcinoma under hormonal treatment].

The evolution of the ultrasonographic images of 25 patients with advanced carcinoma of the prostate receiving antiandrogen (cyproterone acetate) and LH-RH analogue therapy were studied. Thirteen patients were on daily LH-RH analogue therapy while the remaining patients received a monthly depot dose. At 6 months, the ultrasound follow-up revealed a 20.4% reduction of the transverse and a 19.8% reduction of the anteroposterior diameter for the first patient group. Similar results were observed for the second group comprised of 12 patients who received depot therapy; a mean reduction of the diameters of 119.9% and 18.7%, respectively. At 6 months, 66% of the patients in the first group and 59% of the second group showed an improvement of ultrasound patterns. Infiltration of the seminal vesicles improved for both groups, 41% and 38% of patients, respectively. However, at 12 months this rose to 50% improvement for the group on the daily treatment regimen. The follow-up data after 6 months are as yet unavailable for the group on depot therapy. Transrectal ultrasound is an easy, reproducible method that is very useful in the follow-up of patients with advanced cancer of the prostate receiving hormone therapy.

Immunoprophylaxis with Calmette-Guérin bacillus in recurrent superficial bladder tumors.

26 patients with superficial bladder cancer underwent complete removal of tumors by transurethral resection and entered a prospective trial of immunoprophylaxis with Calmette-Guérin bacillus (BCG). The entire group had recurrent tumors that failed to respond to previous prophylaxis with thiotepa (13 patients) or other drugs (13 patients). Intravesical administration of BCG reduced the recurrence index and increased the disease-free interval. Side effects were mild and well tolerated. BCG seems to be effective in the prophylaxis of superficial bladder tumor recurrence after the failure of other drugs.

[Transrectal echography in the infertile male. Statistical study].

We evaluated the transrectal echo patterns in 140 infertile men using the following parameters: the transverse and anteroposterior diameters of the prostate, the presence of periprostatic venus plexus, and the transverse diameter of the seminal vesicles. Patients were classified according to data gleaned from semen analyses following the criteria recommended by the WHO. Microbiological analyses using the Meares and Stamey technics, as well as semen analyses, were performed in those patients who presented with leukospermia. These were considered a separate, homogeneous group classified as "inflammatory". The following patient groups comprised the study: azoospermia (18 patients), oligospermia (4), astenozoospermia (43), oligoastenozosermia (48), and inflammatory (27). Statistical analyses of the ultrasound data for the infertile males and those of the control group were performed using the Mann-Whitney U. test and compared. Data were statistically significant for the following parameters: the transverse diameter for the infertile males with azoospermia, the anteroposterior diameter of the prostate for those patients with leukospermia, and the periprostatic plexus for those in the oligoastenozoospermia and inflammatory patient groups.

[Modification of the echographic pattern of carcinoma of the prostate treated with Lh-rh agonists].

We present the results of a study undertaken to assess the echo patterns and prostate size in 13 patients with prostatic carcinoma treated with Lh-rh agonists. The study revealed a gradual reduction of the anteroposterior and transverse diameters. After 12 months, these were 28% and 22% of their respective initial values. Furthermore, the prostatic echo patterns changed significantly in 66% of the patients, and infiltration of the seminal vesicle improved or became stable in 50%. These findings suggest that transrectal ultrasonography may be useful in the follow up of prostatic carcinoma patients receiving hormone therapy.

Crossed chemoprophylaxis assay between adriamycin and cis-platinum in recurrent superficial bladder tumor.

Of 146 patients with superficial bladder carcinoma, 66 (35 primary and 31 recurrent from failure of thiotepa chemoprophylaxis) relapsed following transurethral resection (TUR) and chemotherapy with adriamycin or cis-platinum. A new TUR was carried out. In case of progression in the number of tumors, size, stage or grade, treatment was begun with the other drug. If the tumor had the same characteristics, treatment was continued with the same drug. In both the primary and recurrent tumors with or without progression, cis-platinum controlled the tumor better than adriamycin, rescuing it from the latter and obtaining a recurrence index and disease-free interval as with cis-platinum alone. These results are more conclusive in primary tumors.

Thiotepa versus adriamycin versus cis-platinum in the intravesical prophylaxis of superficial bladder tumors.

A study was performed on 184 patients with superficial bladder cancer (pTa, pT1), 92 with primary and 92 recurrent tumors. After TUR of all visible lesions, endovesical chemotherapy with thiotepa, adriamycin or cis-platinum was started on the 15th and 30th days following surgery. There were no statistically significant differences between any of the three chemotherapies at the doses and intervals mentioned. Only cis-platinum has proven to be more effective in primary high grade tumor.
