[Extracorporeal shockwave lithotripsy in single kidneys. Our experience].

Forty patients with renal lithiasis in single kidney were treated with extracorporeal shock wave lithotrity in our unit. Nine patients required emergency urinary by-pass, because of original picture of obstructive anuria, and in another 21 cases a double-J catheterism was conducted as prophylaxis prior to lithotrity. Treatment was carried out with analgesia and ambulatory, except for 10 patients with calculi of less than 10 mm where by-pass was not performed, and who were kept in preventive hospitalization for 24 hours. Average of sessions per patients was 1.59 (range 1-7). After 6 months follow-up there are 24 free renal units (60%), 12 (30%) with debris that can be expelled, failure in 4 (10%): 2 with debris that can be expelled and 2 which were not fragmented. Renal function has not deteriorated during follow-up, except for 2 patients with obstructive uropathy, that subsequently normalized following resolution of the condition. No significant differences were found in the treatment of calculi of less than 10 mm with or without double-J. ESWL is considered to be the choice approach for lithiasis in patients with one single kidney, due to is efficacy and low morbidity, safety in the ambulatory environment, even for calculi of less than 10 mm with no urinary by-pass.

[Treatment of prostatic benign hyperplasia with endoscopically controlled laser fiber].

Between October 1992 and February 1993, 12 patients with benign prostate hyperplasia (BPH) were treated with Neodymium-YAG laser through an endoscopically-guided right angle fibre, and follow-up is now over 1 year. Follow-up consisted in the symptomatic assessment using I-PSS questionnaires, vesicoprostate ultrasound with flowmetry and residue measurement and urethrocystometry at least every 3 months. Mean time for suprapubic catheter withdrawal was 23.4 days (range 9-34), and one patient did not resumed micturition spontaneously. Symptomatology improved after the first month. remaining stable after 6 months, with a mean score decrease at one year of 11,2 (p < 0,001). All flowmetry parameters improved although only peak and mid-stream flow showed statistical differences, peak flow increasing at one year by an average of 5,9 ml/sec (P < 0,001). In 4 of the 12 patients surgery was performed; 1 underwent early surgery due to absence of spontaneous micturition and was excluded from the results assessment, and 3 due to persistence of symptomatology at 16, 18 and 21 months post-laser. In spite of the advantages presented by the laser when compared to conventional surgical approaches, such as short time application, absence of haemorrhage and likely used in an ambulatory setting, the major initial irritative symptomatology and the need for a suprapubic catheter during at least three weeks, are in general poorly tolerated and limit its use. The apparent improvement in symptomatology after one month is not accompanied by objective changes in flowmetry, since in our series only 1 patient presented Qmax greater than 15 ml/sec with no residues. Therefore, we consider that treatment with endoscopically-guided laser fibre in BPH has, with the technology currently available. a very limited use.

[Vesicoprostatic echography versus transrectal planimetry in the determination of prostatic volume].

The intention of this paper is to analyze the correlation between two techniques used to measure prostatic volume: transrectal ultrasound with planimetry and transabdominal vesicoprostatic ultrasound. A total of 44 patients have been subjected to transrectal ultrasound, where prostatic volume was determined by planimetry. With this simultaneous technique, patients were performed a vesico-prostatic ultrasound with estimation of volume, achieved by measuring the prostatic diameters and then applying the ellipsoid formula. There were no statistically significant differences between mean values of prostatic volumes as calculated by either technique, both showing a strong correlation (r = 0.817). During transrectal planimetry, the three prostatic diameters were measured and, using a multiple regression study, the influence they have on the changes of prostate's volume was noted. It was observed that it is the transverse, but essentially the longitudinal diameter, the ones which explain those changes (Sig T = 0.0012 and 0.0000, respectively).

[Duplex ultrasound before and after intracavernous papaverine injection in the diagnosis of impotence].

The study of impotentia coeundi requires separating the organic from the psychogenic cause. Arteriogenic impotence falls within the first group and has been assessed with the papaverine test, simple Doppler and arteriography. Currently, more sophisticated techniques such as the pulsed Doppler permit noninvasive assessment of the blood supply to the penile arteries. Intracavernous injection of vasoactive substances such as papaverine cause vascular changes. Evaluation of these changes permits making the diagnosis of arterial insufficiency without recurring to more invasive diagnostic techniques such as arteriography. Currently, this invasive technique is only justified in revascularization surgery but not for diagnosis. The availability of color Doppler facilitates arterial evaluation even further.

[Duplex echography in acute scrotum. Diagnostic possibilities].

Acute scrotum is a frequent reason for consultation at the urological emergency service. The most common causes, apart from trauma, are acute orchiepididymitis, torsion of the hydatids of Morgagni and torsion of the spermatic cord. Apart from a detailed examination of patient history and a careful physical examination, few diagnostic techniques can be utilized. To date, only the Doppler ultrasound has proved useful in corroborating the suspicion of vascular involvement, although this technique is very limited. With the availability of the duplex ultrasound, the possibility of making the differential diagnosis in the acute scrotum is enhanced. This technique permits morphological and functional assessment and avoids unnecessary exploration surgery within the scrotum.

[Renal liposarcoma: diagnostic and therapeutic considerations].

We report on two cases of renal liposarcoma. The clinical features of this tumor type are described and diagnostic and therapeutic considerations are put forward. The usefulness of CT in the diagnosis of this disease entity is underscored. This permits us to evaluate the response to treatment and furthermore, it permits early detection of recurrence.

[Balloon dilatation in tuberculous ureteral stenosis].

We report on a case of tuberculous ureteral stricture submitted to balloon dilatation, a procedure currently advocated by many authors as an alternative to surgical correction in benign ureteral stricture. Transluminal balloon dilatation of ureteral strictures is not a standardized technique, although it follows some essential maneuvers. The procedure can be performed antero or retrogradely and always with temporary internal or external diversion. It is not a harmless procedure, but the complications are scant. However, many aspects have yet to be elucidated.

[Retroperitoneal ganglioneuroma].

We report a case of retroperitoneal ganglioneuroma that had been incidentally discovered during ultrasound evaluation in a young female patient. The plain X-ray, IVP and ultrasonography only revealed the presence of a retroperitoneal mass and its approximate size. CT and arteriography provided further information relative to the location, nature of the extrarenal mass, its borders, and size although these did not permit us to determine its origin.

[Value of bone gammagraphy and pain in the follow-up of carcinoma of the prostate].

We reviewed 382 bone scans from 161 patients with prostatic adenocarcinoma submitted to scintigraphic evaluation over the period 1980 to 1988. Each patient had a mean of 2.37 bone scans (1 to 9 scans). Seventy-three patients had positive scans (64 initially and 9 in the course of patient follow-up). Sixty-four presented bone pain (56 initially and 8 in the course of the disease). The remaining 17 patients were asymptomatic throughout follow-up; however, bone metastasis was undemonstrable. In our view, pain is a reliable indicator of the appearance or progression of bone metastasis. Routine follow-up bone scans are unnecessary in patients with positive or negative scintiscans who remain asymptomatic.

Appearance of gas in renal tissue after therapeutic embolization.

We present a case of therapeutic embolization in a patient with adenocarcinoma who demonstrated the presence of gas in the renal infarcted tissue on the second day. The pattern of air distribution was intravascular. There was no sign of abscess clinically or radiographically. To the syndrome of postembolization we add a new sign--the presence of postembolization air.

[Diagnosis and treatment of coital penile injury].

Two cases are presented of non-penetrating coital trauma of erect penis. This is a rare pathology. No prospective studies are therefore available, but instead there is much controversy. We review the existing literature as well as the various diagnostic and therapeutic attitudes and we propose an algorithm to systematize its management.

[The phenomenon of obstructive uropathy with minimal or no dilatation].

Obstructive anuria does not necessarily show a marked dilatation of the urinary tract on evaluation with imaging techniques. A case with acute renal failure of this type is presented. We discuss why this condition is caused and how diagnosis can be made quickly. Likewise, we discuss the length of time we can defer renal diversion before rupture of the collecting system supervenes and, consequently, urinary extravasation.

[Adenocarcinoma of the kidney pelvis].

We present a case of primitive renal pelvis and calix adenocarcinoma. The clinical evaluation was carried out by means of UIV, echography and TC. Although the tumoral type diagnosis is histologic, the clinical manifestations of chronic renal infection-inflammation, whether associated with obstruction and/or lithiasis or not, are suggestive of this possibility.
