No full textThe subcoronal approach is the most widely used skin degloving procedure for corporoplasty. Although it is relatively easy and it fully exposes the corpora cavernosa, it is not free from several complications (subcoronal lymphedema, decrease of glans sensitivity, paraphimosis, distal skin necrosis), which sometimes require a postoperative circumcision, or a preoperative prophylactic circumcision.To describe our own degloving approach, the "Trans-scrotal Penile Degloving (TPD)", that is suitable for most corporoplasties, and to present the outcomes.This is a retrospective analysis conducted on 89 patients (pts) presenting with different penile diseases, and submitted to the TPD during Corporoplasty, from February 2008 to July 2010: Congenital curvature (26 pts); Peyronie's Disease (PD) with penile curvature (18 pts); PD with erectile dysfunction and curvature (25 pts); Redo surgery with complex tunica albuginea remodeling and prosthesis implant (20 pts). The TPD approach calls for a 5 cm incision to be placed ventrally on the scrotal raphe at the penile base: penile degloving is then easily carried out up to the coronal line. Subsequently, the dorsal neurovascular bundle is normally isolated and all types of different corporoplasties can be carried out.Any complication occurring during or after surgery has been registered. Patient follow-up controls were performed on day 7, month 1 and month 3 post-surgery: -No pre- or post-operative circumcision procedures were required; -There was no evidence of post-operative preputial edema or penile skin necrosis or loss of glans sensitivity; -In 6 patients, we noted a mild scrotal sub-dartos hematoma, which reabsorbed spontaneously.TPD, which represents an evolution of our previous combined subcoronal-trans-scrotal approach, may be advantageously performed in most corporoplasties with optimal aesthetic and functional outcomes, and may replace in many cases the subcoronal approach without its associated complications
The new transperineal-prerectal approach in posterior urethroplasty
No full textObjective: A new posterior urethroplasty is suggested for patients with pelvic fracture urethral distraction defect (PFUDD). Methods: 12 men, with PFUDD were treated with an anastomotic urethroplasty, using a transperineal-prerectal approach. All patients had a suprapubic tube in place and were impotent after pelvic trauma. The goal of this approach was to facilitate an extensive removal of the scar tissues around the prostatic apex to promote successful bulbo-prostatic anastomosis. Results: No patients had intraoperative, perioperative or postoperative complications. Urinary incontinence or rectourethral fistula was never observed. In 11 patients the postoperative mean peak flow was 20 ml/sec. The recurrence of the stricture occurred in 1 patient. Conclusions: The transperineal-prerectal approach to the posterior urethra facilitated a free tension posterior end-to-end anastomosis, as an alternative to the transpubic anastomotic procedure
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Long-term follow-up of blood pressure after extracorporeal shock wave lithotripsy
No full textThirty-five men and 33 women, mean age 45 years (range 15-67) treated with extracorporeal shock wave lithotripsy (SWL) for renal stones by a modified Dornier HM3 lithotripter, were followed in a 24- to 36-month prospective study to assess the risk of hypertension. No significant increase in the mean diastolic blood pressure was observed. No correlation was found between the hypertension incidence and the number of shock waves applied, the kilovoltage, urinary N-acetylglucosaminidase variations, or initial blood pressure. Among the normotensive group, three new cases of hypertension (diastolic pressure of greater-than-or-equal-to 100 mm Hg) were observed (6%), which was not significantly greater than expected. Nevertheless, we believe that long-term surveillance is essential after SWL
Laparoscopic treatment of renal cysts
No full textFour patients underwent laparoscopic resection of extensive (8–15 cm) inferior and medio-renal polar cysts of the kidney. The average operating time was 2 h. The operation is performed with the patients lying in a lateral decubitus position, and requires four incisions for access. The laparoscopic resection of renal cysts can be proposed as a valid alternative to standard surgical treatment as well as percutaneous hollow-needle aspiration
Validity of superficial echography in the study of urethral pathology
No full textIn male patients routine examination for urethral disease includes retrograde and anterograde urethrography and urethroscopy. In the patients underwent radical cystectomy, detection of cancerous cells in the urethral washing suggest cancer relapse. Nowadays we can achieve a sonographic study of the anterior male urethra, using a superficial high frequency ultrasound probe. Since September 1992 till July 1993, 12 patients underwent cystectomy at our Institution and 13 patients affected by urethral stricture, have been investigated by routine examination and sonographic urethrogram. In the first group of patients, out of 3 patients with urethral tumor, sonourethrography has confirmed the presence of tumor in 2 cases. In these second group of patients, sonourethrography has located the stricture, evaluated the length, calculated the diameter of the stricture and the depth of fibrosis. Sonourethrography is a non-invasive method that can provide valuable information about the urethral lumen and the urethral wall
