Total anterior urethral reconstruction with the 'BAES flap' in a spinal cord-injured patient.

STUDY DESIGN: A case report of urethral destruction in a spinal cord injured (SCI) patient. OBJECTIVES: To report the reconstruction of the whole anterior urethra in one-stage using an epilated scrotal flap. SETTING: Institut Guttmann, Hospital de Neurorehabilitació, Barcelona, Spain. METHODS: A one-stage tubular substitution urethroplasty based on a bi-axial epilated scrotal flap design ('BAES flap') was performed successfully. RESULTS: Long-term follow-up of 6 years has confirmed the excellent adaptation of the flap to its urethral function. CONCLUSION: The bipedicle epilated scrotal flap can effectively resolve this challenging urethral pathology.

A new biaxial epilated scrotal flap for reconstructive urethral surgery.

PURPOSE: We describe a new type of perineum based scrotal flap with biaxial vascularization supplied by both superficial perineal arteries. Flap length of up to 20 cm. may be attained for urethral reconstruction. MATERIALS AND METHODS: A total of 37 men with complex urethral stenosis of different etiologies underwent surgery using 1 of 3 urethroplasty techniques based on this new flap. The whole anterior urethra, including pendulous and bulbar segments, was reconstructed with a scrotal patch in 10 patients. A scrotal tubular flap was used as a substitute for the bulbar urethra in 7 patients and for the membranous portion in 4. Bulbar urethroplasty with a scrotal island patch was performed in 16 patients. RESULTS: Of the patients 86% achieved normal voiding after 1-stage urethroplasty. Mean followup was 39.5 months. CONCLUSIONS: The excellent axial vascularization of this new flap permits successful resolution of the most complex urethral stenoses regardless of extension, location and etiology.

Scrotal flap epilation in urethroplasty: concepts and technique.

PURPOSE: We describe our technique of scrotal epilation and the advantages of using the resultant glabrous scrotal skin in reconstructive urethral surgery. MATERIALS AND METHODS: An insulated needle model adapted to scrotal hair characteristics and a thermocoagulation current generator were used. RESULTS: An average of 3 epilatory sessions with a 4-week interval between treatments was the optimal schedule. No cutaneous infection was noted. CONCLUSIONS: The good results permitted the conversion of predetermined scrotal zones into wide areas of alopecia to be used as excellent skin flaps in complex urethral stenosis surgery in postpubertal male patients.

Ejaculation in men: a dynamic endorectal ultrasonographical study.

OBJECTIVE: To study the ejaculatory mechanisms in men using a dynamic endorectal ultrasonographical approach. SUBJECTS AND METHODS: Seven recordings were made of a young healthy volunteer during ejaculation, scanning the longitudinal plane from the bladder neck to the bulbous urethra. RESULTS: The study demonstrated the existence of a pre-ejaculatory phase characterized by a notable decrease in echogenicity of the inner prostate gland, due to the contraction of the pre-prostatic sphincter 13-25 s before ejaculation. Several stages were recorded including an ejaculatory stage with an initial prostatic emission phase lasting 2-20 s and a posterior emission phase through the ejaculatory ducts lasting 3-14 s, with a seminal stoppage of 3-8 s, and finally a urethro-vesical reflux of a minimal fraction of the ejaculate over 5-9 s. The bladder neck and inner gland returned to their resting configuration between 10 and 90 s after ejaculation. CONCLUSIONS: Endorectal ultrasonographical imaging during ejaculation, a recently developed diagnostic procedure, may provide a new approach to ejaculation-related problems.

[Current controversies on the treatment of urinary lithiasis].

With the discovery during the 1960s of an access to the renal sinus and intra-operative radiological monitoring, the lithiasis surgery reached its summit of technical perfection. A comparative study on the various therapeutical options is presented: NLP, URN, ESWL and open surgery, as the single or combined treatment in complex renal lithiasis. Also, intrasinusal and transparenquimatous accesses to the intrarenal tract are compared, evaluating the morbidity, surgical time and economical interpretation of both techniques. Establishment of each treatments' indications and contraindications as well as likely short- and long-term adverse effects of the new technologies.

Orthotopic renal transplant and results in 139 consecutive cases.

Although a commonly performed technique, heterotopic renal transplantation may be a cause of late graft failure owing to ureteral stenosis, urinary fistula and vesicoureteral reflux secondary to the immune response. The new retroperitoneal lumbar approach to the splenic vessels has allowed the orthotopic technique to be developed using the splenic artery or aorta, the renal vein and a pyelo-pyelic anastomosis. In this manner the renal graft is located in an anatomical position that is well protected, and with the recipient urinary tract the normal physiology is preserved with comparatively low complication and mortality rates. A third transplant attempt also is simplified. This method is the only alternative in some cases. Transplant ureter pathology symptoms are not observed. The results of 139 consecutive cases are presented.

New surgical approach for treatment of complex vesicovaginal fistula.

Complex vesicovaginal fistulas still represent a management problem, since most of the cases have been operated on previously and because of the lack of a completely successful surgical technique. A new procedure for vesical autoplasty is presented. A flap is obtained from the posterosuperior bladder wall that slides down to cover large lesions, even in low capacity reservoirs. The technique has shown excellent long-term results in 42 consecutive complicated cases.

[Cyst of the prostatic utricle].

Presentation of a case of prostatic utriculus cyst which due to its size and the patient's history suggested a differential diagnosis with a urethral or vesical diverticulum. Awareness of frequent association to urethral malformations and azoospermia would be very useful when choosing a treatment strategy in such cases.
