[Tridimensional echography: a new urologic challenge].

OBJECTIVE: To describe the urological applications of three-dimensional ultrasonography, a new method that basically transforms the two-dimensional into three-dimensional images through complex data processing for enhanced imaging. METHODS: Since the technology for three-dimensional studies was incorporated into our US equipment a few months ago, we have performed three-dimensional US after the conventional two-dimensional study in 30 renal units, 15 bladders and 15 prostates, using the same well-established procedures for ultrasound assessment. The images obtained by both methods were compared to determine the diagnostic enhancements, if any, afforded by this new technology. RESULTS: Three-dimensional US offers more possibilities for renal cortical volume measurement and determination of the extent of the tumor. It also appears to be promising in regard to its capacity to determine the degree of tumor infiltration in the bladder and permits even more precise measurements of residual volume or bladder content. Transrectal ultrasound of the prostate may benefit more since three-dimensional US permits analysis of focal changes from different perspectives and planes without difficulty. CONCLUSIONS: Three-dimensional US was developed recently. It has been utilized in gynecology and cardiology, but there is limited experience in urology. We have started a clinical study to determine its possibilities and main applications in our field. Its impact on other diagnostic parameters or biopsy selection criteria are other interesting areas of research.

[Prostate leiomyosarcoma with perineal exophytic mass].

Report on one case of prostate leiomyosarcoma, an infrequent and usually highly aggressive urologic neoplasia. Emphasis on the imaging and pathoanatomical diagnosis, highlighting the high value of the later as immunohistochemistry is usually essential to establish its nature. Choice treatment is oncologically radical surgery. Quite often this is impossible to carry out and so chemo- and radiotherapy schedules are commonly associated as neoadjuvant, adjuvant or palliative therapies. The reported case showed aggressive evolution unresponsive to management. Also, during the condition development a rare complication such as occurrence of an exophytic tumoral mass in the perineum appeared.

[Natural history of cancer of the kidney: iconographic follow-up].

OBJECTIVE: To describe the natural history of renal cancer based on the images obtained in a case with more than 11 years' follow-up, from the initial stages of the disease to its outcome. METHODS/RESULTS: The history of a female patient in whom a renal mass had been detected at age 25 years is described. The patient died 11 years later due to metastasis. The images obtained throughout follow-up clearly illustrate the natural course of the disease, which could not be changed because the patient had refused surgery. CONCLUSIONS: The observation of a small renal mass in young patients is an indication for early surgery. The natural course of this disease is predictably fatal, its benign behaviour being highly questionable. Because pregnancy does not appear to accelerate the course of the disease, patient assessment can be completed and treatment can be instituted after delivery.

[Impact of Spanish-language urological publications in periodicals in the English language].

OBJECTIVE: A study was conducted to analyze the impact of the articles published by Spanish authors in the English language urological journals and those published in Spanish journals in the bibliography referenced in the English language urological literature. METHODS: We randomly analyzed volumes 147, 39 and 69 of the Journal of Urology, Urology and the British Journal of Urology, respectively. All articles in the foregoing volumes were reviewed and analyzed as follows: sections, country, no of references, no of Spanish publications referenced, no of references of Spanish publications and the number of Spanish references cited in these. RESULTS: 356 articles were published in the Journal of Urology: of these, 59% were by American and only 6 (1.68%) were by Spanish authors, which ranked 8th according to number. These 6 articles by Spanish authors cited 84 references; of these, only 3 were Spanish publications. Overall, there were 6,708 references (mean 18.8); 6 (0.11%) were articles published by Spanish authors. In Urology, 140 articles were published: of these, 75% were by American and only one (0.71%) by Spanish authors, which ranked 6th according to number. This article by Spanish authors cited 38 references; of these, only 3 were Spanish publications. Overall, there were 2,055 references (mean 14.6); only 8 (0.38%) were articles published by Spanish authors. In the British Journal of Urology, 177 articles were published: of these, 96 (54.2%) were by British authors and only one (0.56%) by Spanis authors, which ranked 9th according to number. This article by Spanish authors cited 11 references; none of them were Spanish publications. Overall, there were 1,988 references (mean 11.2); 14 (0.7%) were articles published by Spanish authors. CONCLUSION: Spanish authors are not worse off than those of other neighbouring countries in regard to the number of articles published (1.18%) in the three journals analyzed, where most of the articles were chiefly by American or British authors. Spanish publications have no impact in the English-speaking countries, although the number of Spanish publications has been slowly but steadily growing and currently account for 1.21% of the publications worldwide: 41.5% of these are referenced in the Science Citation Index and the Uro-Andrological publications rank 6th (4.2%). Moreover, when Spanish authors are able to publish articles in the English-language journals, they rarely reference Spanish publications. However, in proportion, these have more impact than the Spanish publications. The current trend in the prevalence of the English language in the scientific field is probably the cause of the nonexistent impact outside Spain, where they are hardly-read by the Spanish-speaking communities. The foregoing situation is further assisted by the fact that indexing is also done in the English language. Spanish authors are encouraged to increase the number of Spanish publications referenced, particularly those publishing articles in the foreign journals.

[Fracture of the penis: two new cases. Review of the literature. Usefulness of echography].

OBJECTIVE: To analyze the diagnostic and therapeutic difficulties in rupture of the albuginea penis and review the literature. METHODS/RESULTS: Two additional cases of penile rupture are described. Penile ultrasound evaluation disclosed a hematoma in the corpus cavernosum in one case and hematoma and a probable rupture of the albuginea penis in the other case. Treatment was by immediate surgery which achieved good cosmetic and functional results. CONCLUSIONS: Penile fracture is an uncommon condition which occurs when the penis is in erection. Ultrasound is useful in its diagnosis, but MRI is more precise. Treatment is by immediate surgery to avoid sequelae, which are common in cases treated conservatively.

[The role of video voiding cystourethral sonography in the study of the urethrovesical anastomosis following radical prostatectomy].

OBJECTIVE: The sonographic anatomy of the urethrovesical anastomosis in patients submitted to radical prostatectomy is described herein. METHOD: Video sonographic voiding cystourethrography was performed using a 7.5 MHz linear-array transrectal probe. RESULTS: The longitudinal ultrasound scans of the urethrovesical anastomosis during the different phases of micturition are shown. CONCLUSION: Video sonographic voiding cystourethrography is useful in the evaluation of the urethrovesical anastomosis after radical prostatectomy, at rest and during micturition. It also permits detecting any postoperative complication as hematoma, abscess or early recurrence.

[Brucellar orchitis. Report of a series of 16 cases].

A retrospective study of orchiepididymitis, diagnosed and admitted to our Unit over the 1989-94 period was conducted. there were 125 orchiepididymitis, of which 16 (12.8%) had a brucellar etiology, and three had simultaneously become abscessified (18.75%). Considering that our working area is located within an endemic region, and even more, our province has the country's highest incidence rate (112.8/100000 inh.), this prompted us to study the conditions' morbidity in the testicular location, while we make a superficial revision of this disease. Brucellar orchitis is a diagnostic option to be taken into account in endemic regions, and the clinical picture associated to the orchiepididymal process should make us suspect its diagnosis and trigger follow-up of these patients.

[Abscessed brucellar prostatitis. An infrequent location].

Explanation of one case of abscessified brucellar prostatitis in a 44-year old patient. The emphasis is placed on the high incidence of brucellosis in the province of Soria and the rarity of the prostatic location of this condition. Also, a revision is made of the diagnostic methodology and current therapeutical approaches. The crucial role of the endocavitary ultrasound techniques both for diagnosis as well as treatment and case follow-up is highlighted.

[Ultrasonography diagnosis of ureteral ectopy in prostatic urethra].

A 54-year-old male who consulted for an episode of right-sided nephric colic is described. A urological ultrasound scan disclosed grade I hydronephrosis in the upper half of the right kidney and an anechoic tubular image ending in the prostate gland. A subsequent urographic evaluation confirmed the diagnosis of ectopic ureter in prostatic urethra.

[Renoduodenal fistula secondary to pyonephrosis].

Presentation of one case of renoduodenal fistula due to pyonephrosis in an oligophrenic female patient. In view of the patient's characteristics, the clinical picture was highly developed at presentation which resulted in failure of the conservative treatment. We emphasize the diagnostic and therapeutical methodology followed. Also, we include a literature review on this disease.

[An evaluation of the diagnostic efficacy of video cystourethrosonography].

Evaluation of the diagnostic capacity of lineal ultrasound examination of a male's vesical neck and urethra, known as video cysto-urethro-sonography. The tests has been shown to have high diagnostic accuracy (93.6%), with 93.4% overall sensitivity and 94.4% specificity, in a selected group of men with suspicion disease in the cervico-prostate-urethral area (prevalence, 80.9%). The technique, nevertheless, is not exempt from limitations, including anal or ureteral meatus stenosis, as well as highly obstructive prostate adenoma (where maximal vesical repletion necessary to carry out the examination may decompensate the picture, and lead to retention), or the inhibition of the voiding urge referred by certain individuals when they have to urinate in uncomfortable circumstances.

[The technical aspects of video cystourethrosonography].

Analysis of major methodological aspects of real time ultrasound examination of a male's vesical neck and urethra, known as video cysto-urethro-sonography (VCUS). Consideration must be given, when studying the posterior urethra, to the need of suitable vesical repletion, as well as to the existence of two likely limitations for conducting the test, such as: major anal stenosis, which would prevent introduction of the transrectal transducer; and inhibition of the voiding urge referred by some patients when they have to urinate in uncomfortable circumstances. As for the study of the anterior urethra, the most interesting technical items are: avoidance of air bubbles entering with the physiologic serum, which could artefact the examination; nonexertion of excessive compression on the urethra with the transducer, which may lead to false stenosis; and understanding that a major meatus stenosis may preclude test completion due to impossibility of introduction of Foley's catheter, necessary to obtain backward urethral distension with physiologic serum.

[Simple calculation of prostatic weight with transrectal echography].

The appraisal of the prostate weight with transrectal ultrasound scanning is simplified with the use of a simple mathematical formula of an ovoid volume. Such a method does not prolong the examination time but provides an acceptable reliability, and therefore it can be used as a substitute to planimetry, more subject to the observer's error and more time consuming for the physician, even when part of the examination can be made by replaying the video.

[Ureteral ectopy: report of a case of ureteral communication with vulva].

We report an uncommon case of ureteral ectopia opening to the contralateral vulva in a 20-year-old patient with a long history of night and day urinary incontinence. Since the ectopic ureter drained the superior pelvis of the right kidney, pyelo-pyelic anatomosis was performed and the defunctionalized ureter was abandoned. A completely satisfactory result was achieved. We briefly discuss this rare pathology and describe the simple, yet effective treatment.
