[Erectile dysfunction caused by neurapraxia of the pudendal nerve after the use of a traction table for the treatment of traumatic fractures. Report of a case and review of the literature].

OBJECTIVE: To describe a case of erectile dysfunction as a result of traction on the fracture table. METHODS: We report on a 39-year-old man who developed erctile dysfunction postoperatively and for several months thereafter, following intramedullary nailing with the Grosse-Kept bolt type fixation system. RESULTS: The patient spontaneously recovered erectile function six months after orthopaedic treatment. CONCLUSION: Erectile dysfunction induced by orthopaedic fracture table is a complication that should be taken into account. There are many procedures available to reduce the risk of this complication.

[Urologic iatrogenic disease].

OBJECTIVE: The purpose of this paper is to emphasize that despite the undeniable advantages of urological instrumentation (insertion of a ureteral catheter, double-J catheter; percutaneous nephrostomy, etc.), it also carries some risks and complications. METHODS: We report three cases of iatrogenic urological complications due to use of endoscopic and percutaneous material. RESULTS/CONCLUSION: Urologists, and particularly the residents, are reminded that iatrogenic complications may occur even in the easiest and routine procedures of the medical activity.

[Acute orchiepididymitis: assessment with high-resolution ultrasonography in 52 cases].

OBJECTIVES: The present study describes our experience in ultrasound diagnosis of acute orchiepididymitis, with special reference to the most common US patterns and complications of this disease entity. METHODS: In acute scrotum suspected as having an inflammatory origin, high resolution ultrasonography is performed in the acute phase in addition to routine blood and urine analyses. Treatment and subsequent US control evaluation vary according to each case. RESULTS: The sonographic findings in 52 cases with a clinical suspicion of acute orchiepididymitis are presented. All examinations were performed in the acute phase. Subsequent sonographic control evaluation was performed 2-4 months after treatment. Seven cases had a negative ultrasound; in 4 cases ultrasound disclosed a different pathology (2 tumors, 1 testicular torsion and 1 hydatid torsion); 12 had both testicular and epididymal involvement; one had testicular and 28 had epididymal involvement alone. Complications were observed in 21 cases (hydrocele, abscess, pyocele, infarct...). Sonographic evaluation after treatment showed complete resolution in 26 cases whereas 15 cases showed postinflammatory sequelae (atrophy, changes in testicular ultrasound pattern, calcifications, chronic hydrocele...). The ultrasound findings indicated surgery in 2 cases. CONCLUSIONS: High resolution ultrasonography is currently the diagnostic method of choice in scrotal inflammation. It permits determining the extent of the lesion (orchitis, epididymitis, orchiepididymitis), complications (hydrocele, hematocele, pyocele, abscess, infarct...) and the result of therapy.

[A new case of entero-vesical fistula, secondary to Crohn's disease].

OBJECTIVE: To emphasize that urological symptoms and signs can be the presenting features of Crohn's disease. METHODS: A case of enterovesical fistula in a patient with Crohn's disease is described. The patient presented with hematuria and mild voiding symptoms, but there were no GI or other symptoms. The clinical aspects, diagnostic methods (ultrasound, cystoscopy, rectosigmoidoscopy) and treatment are discussed. RESULTS/CONCLUSIONS: Although Crohn's disease is rare, it should be considered when making the differential diagnosis in patients who present with voiding symptoms and hematuria.

[Giant bladder diverticulum, inside inguinal hernia. Clinical case and review of the literature].

OBJECTIVE: To report a case of giant diverticulum of the bladder associated with inguinal hernia. METHODS/RESULTS: An uncommon case of giant diverticulum associated with inguinal hernia is presented and the literature reviewed. The enormous size of the diverticulum and the associated lower urinary tract obstruction arising from hyperplasia of the prostate required resolution of both conditions. This was achieved by diverticulectomy with herniorrhaphy and TURP. CONCLUSIONS: Diverticula of the bladder are associated with lower urinary tract obstruction that are generally caused by a prostatic condition. Hernia with bladder diverticulum is uncommon. The symptoms are usually scanty and cannot be distinguished from the voiding symptoms arising from prostatic involvement. Apart form the clinical findings, US, cystography or IVP are useful for diagnosis. Treatment is usually by surgical correction of both the bladder diverticulum and voiding obstruction from prostatic hyperplasia.

[Gas-containing balano-preputial abscess; diagnostic and therapeutic approach].

OBJECTIVE: A case of balanopreputial abscess containing gas in a patient with adhesion of the glans penis to preputial mucosa is presented. METHODS: The clinical features, diagnostic methods (penile ultrasound) and treatment (debridement + step (staged?) circumcision) are described. RESULTS/CONCLUSIONS: Severe phimosis and balanopreputial adhesions can cause urological complications as shown in the case described. Ultrasound demonstrated the presence of abscess and gas.
