A new MDCT technique for the detection and anatomical exploration of urogenital fistulas.

Objective: We tested a new MDCT technical protocol, combining i.v. and intravesical positive contrast agent and intravaginal neutral contrast agent, that optimizes exploration of urogenital fistulas.

[Medical therapy for ureteral stones: high versus low fluid intake].

The mainstays of renal colic medical treatment are first to provide efficient pain relief, and second to facilitate migration of the ureteral stone or dissolve it. In the ambulatory setting, non steroidal anti-inflammatory drugs are the treatment of choice of pain relief. To facilitate stone migration, the debate between hydric restriction and hyperhydration remains somewhat open.

[Indications for low-dose CT in the emergency setting].

CT delivers a large dose of radiation, especially in abdominal imaging. Recently, a low-dose abdominal CT protocol (low-dose CT) has been set-up in our institution. "Low-dose CT" is almost equivalent to a single standard abdominal radiograph in term of dose of radiation (about one sixth of those delivered by a standard CT).

Laparoscopic treatment of mucinous urachal adenocarcinoma with mucocele.

We present a case of an asymptomatic 76-year-old woman treated laparoscopically for an urachal mucocele owing to a nonmetastatic urachal mucinous adenocarcinoma. Since laparoscopic en bloc resection of the urachus and partial cystectomy, the patient has been healthy and disease-free for 12 months. Modern surgical treatment of urachal adenocarcinoma is discussed in the light of this case.

Percutaneous cryoablation of small kidney tumours under magnetic resonance imaging guidance: medium-term follow-up.

Objective: Minimally invasive treatment of small kidney tumours remains a challenge. Cryoablation has recently been advocated for such neoplasias. However, few series evaluating this therapeutic regimen are as yet available.

Blood splash injury: an underestimated risk in endourology.

Background And Purpose: Mucocutaneous and transconjunctival exposure are important portals for the transmission of blood-borne infections to surgeons and health-care workers. Despite this knowledge, few surgeons or their assistants wear protective equipment for procedures perceived to be affiliated with less risk. This study investigates the potential risk of mucocutaneous and transconjunctival blood splash injury during common laparoscopic and endourologic procedures undertaken using standard video endoscopy equipment.

[Treatment of symptomatic prostatic hypertrophy with the KTP-80 laser].

Macroscopic per and post-operative hematuria contributes significantly to hospitalisation time and to the morbidity of conventional surgery of symptomatic prostatic hypertrophy. It requires in fact transient anti-coagulation interruption, so as eventually a window with platelet anti-agregants. The newly available 80-Watts Potassium-Titanyl-Phosphate laser markedly reduces post-operative hematuria, and allows operating the increasing population of patients under platelet anti-agregants, or event those who need therapeutic anticoagulation.

[The therapeutic dilemma of the early invasive bladder cancer].

Transitional tumours of the bladder are classically divided in superficial (lesions of the mucosa and the submucosa) and invasive (infiltrating the detrusor) cancers. However, the recurrence and progression rate of submucosal urothelial cancers is highly variable. Therefore, management of such neoplasias is very challenging, some patients requiring a cystectomy, whereas others can be managed less invasively with endoscopic resection eventually associated with intravesical chemotherapy.
