Correlation of endoanal sonography with cross-sectional anatomy of the anal sphincter

1999

Abstract Background: Anal endosonography has become an important imaging method in the diagnosis of anorectal disorders. However, little information exists as to whether anal endosonography reliably defines pelvic floor structures. The aim of this study was to correlate endoanal sonography with cross-sectional anatomy and histology. Methods: Endosonographic tomograms were obtained from 9 human cadavers before fixation and cross-sectioning at identical levels. Muscular layers were defined by visual inspection, histology, immunohistology, and morphometry using three-dimensional sphincter reconstructions. Results: Endosonography visualized only two muscular layers, whereas anatomic sections al…

Suture Materials: Do They Affect Fistula and Stricture Rates in Flap Urethroplasties?

2003

<i>Introduction:</i> The effect of suture materials on urethroplasty complications is debated. Indeed, materials with a delayed absorption might either reduce the incidence of fistulas by ensuring a prolonged approximation of neo-urethral edges or increase the risk of urethral strictures due to a prolonged tissue reaction during suture absorption. We retrospectively evaluated the role of suture materials in the complication rate of urethroplasty procedures performed in our institution over a 10-year period. <i>Patients and Methods:</i> Three hundred and thirty-six boys undergoing a flap procedure (parameatal based, preputial tube, or onlay preputial flap) for hypospa…

Extraprostatic Spindle Cell Stromal Tumor of the Prostate: Case Report

2007

Several benign and malignant nonepithelial and stromal-like lesions arise in the prostate. Because such lesions are rare, their recognition is essential, because treatment and prognosis depend on an adequate pathohistologic classification. We report a case of an 83-year-old man with a stromal tumor of the prostate of uncertain malignant potential (STUMP). He presented with urinary retention and rectal constipation. On bimanual examination, a rectally and suprapubically palpable mass was found. Imaging studies revealed a 12 x 8 cm pararectal inhomogeneous mass of uncertain origin compressing rectum and urethra. The tumor was resected by a retropubic approach and examined immunohistochemicall…

Evaluation of urodynamic studies by computer

1978

In an attempt to simplify urodynamic evaluation, the data obtained from cystometry, urethral profile and flowmetry were analysed using the ICS recommendations for standardization and terminology. All studies were compiled from check lists feasible for computation. The aim was to establish standards and "typical" changes for the normal bladder and pathological states to enable automatic readout of computed data. The results did, in fact, show "typical" changes but failed to establish standard measurements suitable for completely computed diagnoses.

PROSTATOSYMPHYSEAL FISTULA AFTER TRANSURETHRAL RESECTION OF THE PROSTATE

2001

The formation of a urethrosymphyseal fistula is a rare complication after transurethral resection of the prostate. It may develop secondary to previous radiation therapy of the pelvis. We describe a case of spontaneous fistula formation after transurethral resection of the prostate. CASE REPORT

Fistulae (Rectovaginal, Rectovesical)

1979

The clinical manifestations of a fistula — stool from the vagina, air from the urethra — are often difficult to recognize because the fistulous opening is hidden by the edematous and swollen mucosa. Larger defects occur particularly after radiation therapy and with Crohn’s disease.

Effect of prolactin and the anti-prolactin bromocriptin on the testosterone uptake and metabolism in androgen-sensitive and insensitive canine organs

1976

Prolactin promotes the growth and function of the prostate in low doses, whereas high doses or previous castration reduce this effect. The antiprolactin bromocriptin should reverse the prolactin action. In the castrated dog the highest accumulation of H3-testosterone given i.v. occurred in the prostate as compared with muscle, urethra, penis, liver and kidney. Prolactin pretreatment increased the radiosteroid uptake only in the liver. Converseley, bromocriptin suppressed the tracer incorporation into the liver, but increased prostatic accumulation. The highest testerone reduction occurred in the prostate of the untreated castrated dogs as compared with other organs. Prolactin suppressed 5 a…

Improvement of wound healing after hemorrhoidectomy: a double-blind, randomized study of botulinum toxin injection.

2005

PURPOSE: Hemorrhoidectomy is usually associated with significant pain during the postoperative period. The spasm of the internal sphincter seems to play in important role in the origin of pain. This study was designed to evaluate the effectiveness of intrasphincter injection of botulinum toxin after hemaorrhoidectomy in reducing the maximum testing pressure of the anal canal, accelerating wound healing, and decreasing postoperative pain when resting and during defecation. METHODS: Thirty patients with hemorrhoids of third and fourth degree were included in the study and randomized in two groups. Anorectal manometry was performed preoperatively and 5 and 30 days afterward ill all patients un…

Detection of Subpubic Tumor Causing Bladder Outlet Obstruction by 3D Perineal Ultrasound

2015

This case report shows that 3D perineal ultrasound can be superior to clinical examination and routine 2D perineal ultrasound in the detection of an unusual subpubic tumor. A 73-year-old female patient was referred to our urogynecological outpatient unit complaining of over-active bladder symptoms and voiding dysfunction for 3 years. Gynecological examination found no signs of pelvic organ prolapse or abnormality in the vaginal cavity. Routine 2D perineal ultrasound showed substantial residual urine (ca. 300 ml on catheter) and limited bladder neck mobility, but no signs of pelvic organ prolapse. Use of standardized 3D perineal ultrasound revealed a 24 × 26 × 32 mm spherical, hypoechoic tum…
