[Modificated plication technique of the tunica albuginea in penis curvature correction]. / Técnica de plicatura modificada de túnica albugínea para la corrección de la incurvación peneana.

We present our penile curvature treatment experience in Peyronie's disease and cogenital curvature, using a modificated plication technique of the tunica albuginea with Prolene inverted sutures covered with Vicryl ones. The first suture gives security to the plication and the second one hides the first dots avoiding the nonabsorbable sutures bother.

[Primitive neuroectodermal tumor. Ewing's sarcoma]. / Tumor neuroectodérmico primitivo renal/sarcoma de Ewing.

Primitive neuroectodermal tumor is an extraordinarily rare primary tumor in the kidney and can be mistaken for a variety of other round cell tumors. It is important to recognize each of these entities, because each carries unique therapeutic and prognostic implications. However, accurate diagnosis of these tumors is hindered by their significant morphologic overlap and complicated by their rarity. These neplasm are highly aggressive that tend to recurence and to metastatize. Standard therapy combining surgery, chemotherapy, radiation and genetic therapy. We report a case of primitive neuroectodermal tumor of the kidney in a 50 year old female patient.

[Treatment of erectile dysfunction using intracavernous pharmacotherapy]. / Tratamiento de la disfunción erectil mediante farmacoterapia intracavernosa.

Intracavernous injection of vasodilators has been the greatest diagnostic and therapeutical breakthrough in erectile dysfunction (E.D.). After 15 years experience, these vasodilators have demonstrated efficacy rates over 85%. This suggests that most cases of E.D. are the result of and inability of the smooth muscle to relax. This paper presents an overview of the diagnostic and therapeutic use of intracavernous vasodilating drugs. It includes an extensive review of the literature and our personal series with regard to efficacy, indications, contraindications and side-effects of these compounds. Alprostadil i.c. injection (PGE1) is an effective (> 70%) and safe treatment, and its use has been accompanied by an increased quality of life of patients, with very few side effects. Currently, PGE1 is a first choice drug in the treatment of impotence. When no response is seen, or pain develops after PGE1 administration, a number of vasoactive compounds associations can be used instead (phentolamine + PGE1, papaverine + phentolamine, and papaverine + phentolamine + PGE1). The phentolamine + VIP association has shown encouraging results. Prior to prescribe IC treatment with vasoactive drugs it is necessary to conduct a basic diagnostic study, and advise the patient. If treatment is finally accepted, the performance of adequate training and detailed medical follow-up is crucial.

[Erectile dysfunction]. / Disfunción eréctil.

In Spain, based on the IIEF, 19% of males between 25 and 70 years old present some degree of erectile dysfunction (ED). Therefore, around 2,000,000 Spanish men present this condition and could require medical attention for it. Here, we present an up-date of the most important aspects of erectile dysfunction (pathophysiology, diagnosis and treatment). We review, in detail, the oral treatments and future drugs that are presently in the premarketing experimental phase. Diagnostic and therapeutic management of the patient with erectile dysfunction should be individualized, taking into account the goals of each patient. It is highly recommendable to carry out a basic assessment (comprehensive clinical history, physical examination, recommended lab testing). If previously undiagnosed diseases are discovered (diabetes, arteriosclerosis, etc.) these should be treated and modifiable risk factors should be corrected. There are numerous therapeutic options for the treatment of erectile dysfunction. Replacement therapy with testosterone should only be used in males with ED and low levels of this hormone, under medical supervision. At present, first line treatment consists of the administration of oral drugs (sildenafil, apomorphine). There are two new PDE 5 inhibitors (tadalafil and vardenafil) that will be released on the market 2003, which will provide better selectivity. Moreover, several drugs for oral administration are in the initial phases of research that will facilitate erection via a direct penile action. When oral drugs are contraindicated, are not effective or when they are unpopular with the patient, the second line of treatment is intracavernous injection. Prostaglandin E1 is the initial drug of choice in patients using intracavernous autoinjection for the first time and has a high efficacy. Implantation of a penis prosthesis and penile revascularisation are appropriate for highly selected patients. Psychotherapy can be an option for men with ED of psychogenic origin, either as a monotherapy or combined with sildenafil or apomorphine.

[Rigid ureteroscopy. Results and complications]. / Ureteroscopia rígida. Resultados y complicaciones.

Analysis of results and complications of retrograde rigid ureterorenoscopies (URS) performed in our unit between August 1985 and June 1990. Our series includes 122 URS performed in 106 patients: 68% female and 32% male. A rigid ureteroscopy Storz 11.5 Ch was used. URS indications were: 72% treatment of ureteral lithiasis, 14% diagnosis, 7% treatment of ureteral tumores and 3% other reasons. Treated lithiasis were predominantly located in the pelvic ureter. Overall success in the treatment of lithiasis was 92.86% in "primary" lithiasis, and 71.43% in post-ESWL. URS allowed us to resolve troubles of differential diagnosis in 93.75% of cases. With a complications rate of 19.7%, only 3.28% were considered relevant.

[Cervico-urethro-suspension by the Raz's technique in the treatment of stress urinary incontinence in women]. / Cervicouretrosuspensión según técnica de Raz en el tratamiento de la incontinencia urinaria de esfuerzo en la mujer.

Presentation of our results in the treatment of urinary exertional incontinence in women using Raz's cervicourethral suspension. From January 1991 through December 1995, 87 patients were operated (mean age: 55.64 years; range 36-74). Mean follow-up was 29.4 months. Recovery from incontinence or permanence of minimal occasional leaks due to major exertion were rated as good results and were achieved in 75 cases (86.20%). Percentage of success in patients with mild incontinence was 93.33%; 88.88% in moderate incontinence; and 58.33% in severe incontinence, differences being statistically significant (p < 0.01). No statistical significance was found relative to age, prior incontinence corrective surgery, hysterectomy or association with urgency incontinence. Prior to surgery, 21 patients also had a component of urgency incontinence which disappeared post-surgery in 18 (85.71%) cases. De novo urgency incontinence appeared in 4 (6.06%) cases. Complications seen were 3 vesical perforations (3.44%). 1 urethrovaginal perforation (1.15%), 2 enterocele (3.44%) and 24 patients with transient urinary retention (27.58%). We believe this technique offers long-term successful results with a moderate morbidity rate.

[The early diagnosis of prostate cancer in a selected population. The usefulness of PSAD, PSAD ad. and age-adjusted PSA in patients with a PSA between 4-10 ngr./ml]. / Diagnóstico precoz del cáncer de próstata en población seleccionada. Utilidad del PSAD, PSAD ad. Y PSA ajustado a la edad en pacientes con PSA entre 4-10 ngr./ml.

RATIONALE: Exposition of our experience in the early diagnosis of prostate cancer, based on the initial selection of patients. METHODS: Evaluation of patients from within the area covered by our hospital and seen for signs and symptoms of prostatism. Those with suspicion rectal examination (RE) or PSA greater than 4 ng/ml were further evaluated with transrectal ultrasound and prostate biopsy. RESULTS: Based on the biopsies of 700 patients, prostate carcinoma was diagnosed in 294/700 (42%). 55.72% patients with suspicion RE, and 47.5% with PSA > 4 had cancer. In patients with PSA > 4 and non-suspicion RE, cancer was detected in 16.44%. The percentage of neoplasia in patients with PSA 4-10 ng/ml and non-suspicion RE was 10%. As a result of these findings, 88 radical prostatectomies were performed. PASD and PASD ad. showed significant differences between patients with and without cancer, whether with (+)RE (p = 0.0001) or (-)RE (p < 0.0004), unlike PSA that showed no differences. The diagnostic value shown by PSAD ad. in ROC curves was similar to that of PSAD. Value of age-adjusted PSA was not higher than PSAD. CONCLUSION: Performance of prostate biopsy with a suspicion RE is recommended. If RE shows no suspicion, biopsy should be performed when PSA is > 10 ng/ml, and with PSA 4-10 ng/ml a biopsy is advocated with PSAD > 0.15.

[Erectile dysfunction after radical prostatectomy. Etiopathology and treatment]. / Disfunción eréctil tras prostatectomía radical. Etiopatogenia y tratamiento.

Erectile dysfunction is one of the most common sequela from radical prostatectomy. The authors evaluate the incidence of erectile dysfunction after radical prostatectomy, study the likely causative vascular mechanisms and assess the efficacy of the treatments employed. Two hundred and four (204) radical prostatectomies were analyzed. 163 (80%) patients referred adequate erections prior to surgery. In 82 cases, surgery was performed with the intention of preserving one or both bands. For the remaining cases, radical surgery with exeresis of both bands was performed. Due to secondary erectile dysfunction, 75 patients were studied by preparing: clinical history, laboratory tests, penile neurophysiological studies and intracavernous prostaglandin E1 injection test. Dynamic drug-cavernosmetry was performed in 36 patients. After radical prostatectomy, only 9.2% previously potent patients retained adequate erections. Of the 82 cases where preservation of one or both bands was attempted, 9 (11%) patients retained their erections. Changes in neurophysiological parameters were found in 69.2% cases and general vascular injury detected in 23 (63.8%) patients by drug-cavernosmetry, the main injuries being cavernous arteries insufficiency in 58.3% and veno-occlusive failure in 33.3%. Of the 75 patients studied, 48 accepted the treatment: 40 (81.6%) used intracavernous auto-injection, 8 had penile prosthesis inserted, and one patient uses a vacuum device. Intracavernous Pg E1 auto-injection has provided adequate stiffness in 95% patients and, at 6 months from onset of treatment, a decrease of the minimal effective dose has been seen which is more noticeable in men under 60 and patients who start treatment within 6 months.

[Treatment by a modified plication of the tunica albuginea in patients with congenital penile curvature]. / Tratamiento con plicatura modificada de la túnica albugínea en pacientes con incurvación congénita peneana.

OBJECTIVE: To evaluate the results obtained with management by modified plication of the tunica albuginea in patients with congenital penile incurvation. MATERIAL AND METHODS: Between January 1992 and December 1996, a modified plication technique of the tunica albuginea was used to correct congenital and acquired penile incurvations; the procedure was performed in 27 cases of patients with congenital penile incurvation and 17 patients with de la Peyronie's disease. Mean age was 22.8 years (range 15-40 years), single ventral incurvation being the most frequent (51.8%) type. A modified technique of tunica albuginea plication was used. RESULTS: Complete correction of the incurvation was achieved in all patients (100%), with a low rate of complications. CONCLUSIONS: Modified plication of the tunica albuginea is a simple and effective surgical technique to achieve correction of congenital penile incurvations.

[Intravesical foreign bodies. Review of the literature]. / Cuerpos extraños intravesicales. Revisión de la literatura.

We want to make a literature review about the bladder foreign bodies. This clinical situation is not an usual emergency, but there are a lot of references in urological articles about it. In this article review we want to make a compilation about the symtoms, the different origins of the foreign bodies, and ways of diagnosis and treatment of this pathology. We also want to add our personal experience in a recent case.

[Analysis of our series of kidney transplants: urologic complications and survival]. / Análisis de nuestra serie de trasplantes renales: complicaciones urológicas y supervivencia.

PURPOSE: To review our series of 416 renal transplants, with special reference to the surgical complications and their management. METHODS: From June, 1986 to October 1997, we are performed 416 heterotopic renal transplants, harvested from cadavers. Reconstruction of the urinary tract reconstruction was by ureteroneocystostomy in practically all the cases. RESULTS: There were some urological complications in 80 patients (19.2%). The most common urological complication was obstruction of the urinary tract arising from stenosis (3.3%), lymphocele (4.3%) and clotting (1.2%). 78.1% of these urological complications were resolved by endourological techniques. Urinary fistula was observed in 12 cases (2.8%). Vascular complications in 22 (6.9%), lithiasis in 5 (1.2%), and eventrations in 11 (2.6%). The treatment of these complications is described. The actuarial survival rates were 87.8% and 77.3% at one and five years respectively for the graft, and 92.4% and 83.5% for the patients. CONCLUSIONS: Our surgical complication rate in patients undergoing renal transplantation was 19.2%. The most common complication was urinary tract obstruction from stenosis (3.3%), lymphocele (4.3%) and clotting (1.6%); 78.1% of these obstructive complications were resolved by endourologic techniques. Percutaneous drainage and esclerotherapy of the lymphoceles resolved 66.6% of them. Renal biopsy performed with a 14G needle caused 5 severe hemorrhagic complications. There were no complications when an 18G needle was utilized.

[Urinary diversions and bladder enlargements]. / Derivaciones urinarias y ampliaciones vesicales.

Overall review that offers an integrated insight of the importance and repercussions of urinary by-pass and bladder replacement. Over the last decades there has been a growing interest in the possibility of reconstructing the urinary system and there are now an almost infinite number of surgical solutions. The history of the development of using the intestine for by-passes and the reconstruction of the urinary system is described. The secondary metabolic alterations, the possibility of secondary intestinal tumours and the rudiments of ureterointestinal anastomosis are dealt with. Bladder substitution techniques are highlighted, and the vast experience of the Urology Department of Hospital Miguel Servet explained, including criteria and conclusions that help to choose from the many urological surgery alternatives headed by urinary by-pass and bladder complications.

[Cost-effectiveness comparative study of ceftriaxone verus cefotaxime in the treatment of complicated urinary infections]. / Estudio comparativo coste eficacia ceftriaxona versus cefotaxima en el tratamiento de las infecciones urinarias complicadas.

Prospective, randomized, multicenter study in 267 patients with complicated urinary infection from 9 hospitals nationwide. Drug treatment was either Ceftriaxone 1 g once daily parenterally or Cefotaxime parenteral 1 g 8 hourly for a minimum of 7 days. Patients were clinically, analytically and microbiologically evaluated before and after treatment to assess the efficacy and tolerance of both drug products. To evaluate treatment cost, we used the price of both drugs and the material required for their administration (syringe and disposable needle). 119 patients were excluded from the cost-efficacy evaluation and 148 remained in the study (75 assigned to treatment with Ceftriaxone and 73 to Cefotaxime). Clinical efficacy of treatment was 93% and 87.6% for Ceftriaxone and Cefotaxime respectively (p > 0.05). Cost per patient was 27,347 pesetas for Ceftriaxone and 34,490 for Cefotaxime (p < 0.05).

[Emphysematous cystitis]. / Cistitis enfisematosa.

The presence of gas in the bladder wall and/or lumen (emphysematous cystitis) is an uncommon disease entity that may be caused by infectious organisms. Diabetes and chronic urinary infection are predisposing factors. Its clinical features are unspecific and the prognosis depends on the degree of aggressiveness at presentation. Early diagnosis and treatment (bladder drainage + antibiotics) are very important in order to resolve the condition before severe sequelae are caused. We report on 75-year-old diabetic female with mild emphysematous cystitis caused by Clostridium perfringens which resolved with bladder drainage and antibiotics. The incidence, forms of presentation, pathogenesis, diagnosis and treatment of this condition are discussed.

[Long-term results of the treatment with intracavernous injection of vasoactive drugs]. / Resultados a largo plazo del tratamiento con inyección intracavernosa de drogas vasoactivas.

OBJECTIVES: To evaluate the long-term results of treatment of erectile dysfunction with intracavernous self-injection of vasoactive drugs. METHODS: The study comprised 144 patients treated with intracavernous self-injection. The most common etiologies were arterial (27%), corporal-veno-occlusive (22.2%) and diabetic (17.5%). The mean follow up was 15.6 months (range 12-44) and the total number of injections was 7,190. PGE1 was utilized in 135 patients and papaverine + PGE1 in 9 patients. RESULTS: Patients with psychogenic or neurogenic impotence responded to low doses of PGE1 (9.6 microgram and 8.4 microgram, respectively). Adequate rigidity was achieved in 96% for over 30 min in 90%, and coitus was satisfactory in 92%. There were 20 (13.9%) dropouts and 5 (3.5%) recovered erection. The most important local complications were intense pain (4 pts, 0.05%), prolonged erection (3 pts, 0.04%) and secondary fibrosis without penile curvature (3 pts, 2.1%). Systemic complications were observed in only 4 cases: palpitation (1 pt), headache (1 pt) and dizziness (2 pts). CONCLUSIONS: Patients with psychogenic and neurogenic impotence responded to low dose therapy, whereas those with veno-occlusive impotence required the highest doses of PGE1 or papaverine + PGE1. This pharmacological erection program achieved adequate rigidity in 96% and satisfactory coitus in 92%. There were minimal complications: prolonged erection (0.04%), intense pain (0.05%) and fibrosis (2.1%).
