[Treatment of precalyceal stones of Cacchi-Ricci disease by flexible ureterorenoscopy and Holmium-YAG laser].

Flexible ureterorenoscopy combined with Holmium-YAG laser is an effective and reliable technique for the management of renal stones. Cacchi-Ricci disease is a frequent urological malformation characterized by precalyceal stone formation, for which no preventive treatment is available at the present time. Some complicated forms are difficult to manage because of the technical impossibility of treating these precalyceal stones.

[Flexible ureteroscopy and holmium-Yag laser: material and technique].

Flexible ureteroscopy combined with Holmium-YAG laser is an effective, reproducible and minimally traumatic diagnostic and therapeutic technique perfectly adapted to diseases of the upper urinary tract. This technology must be part of the therapeutic armamentarium of any centre involved in the management of urinary stones. The technical facilities must be complete and adapted.

[Tubulopapillary tumours of the kidney: prognostic value and therapeutic implications of the distinction between type 1 and type 2 based on a series of 58 cases].

Objective: The purpose of this study was to demonstrate the prognostic value of subdivision of tubulopapillary tumours into 2 histological subtypes and to discuss the therapeutic implications.

Materials And Methods: This was a single-centre retrospective study of 58 cases from a series of 414 patients operated for renal cancer between 1988 and 2001 based on review of histology slides (biopsies and operative specimens). The radiological assessment was based on ultrasound reports and review of CT scans.

[Urological problems encountered during pregnancy].

The many anatomical and physiological changes occurring during pregnancy affect the entire urinary tract. These changes can induce various urological diseases, alter renalfunction and can be life-threatening to the foetus and the mother Some changes can persist post partum. Asymptomatic bacteriuria must be investigated and treated to prevent about 40% of pyelonephritis and a twofold higher premature delivery rate.

[Management of blunt trauma of the kidney].

The current management of blunt trauma of the kidney is based on the 5-grade classification of lesions established by the ASST (American Society of the Surgery of Trauma). The indications for imaging are now clearly defined and spiral CT represents the reference examination. Over the last decade, the debate concerning the management of severe trauma has divided the supporters of surgical treatment from those who recommended conservative management.

[Blunt kidney trauma: a ten-year experience].

Objective: The objective of this study is to assess the results of our therapeutic management of blunt kidney trauma in patients hospitalised over the last 10 years.

Materials And Methods: From January 1993 to January 2003, 105 patients were hospitalised in our department for blunt kidney trauma. We retrospectively studied age, gender, injured side, mechanism of trauma (direct, indirect or deceleration), aetiology, presence of associated lesions (visceral, orthopaedic), and clinical and laboratory signs on admission (haematuria, blood pressure, haemoglobin and serum creatinine).

[Prostate-sparing cystectomy: long-term functional and oncological results in a series of 25 cases].

Objective: To decrease the risk of erectile dysfunction and incontinence by performing prostate-sparing cystectomy for bladder cancer; and to evaluate the oncological results by comparing them to those of radical cystectomy.

Materials And Methods: Since 1994, 141 men have undergone cystectomy for bladder cancer. Twenty five patients with a mean age of 57 years (range: 47-75 years) underwent prostate-sparing cystectomy.

[Early revascularization by stent in renal pedicle trauma].

Objectives: Lesions of the renal pedicle after blunt trauma of the abdomen are rare, and the results of the various therapeutic approaches are unpredictable and usually disappointing. We therefore decided to evaluate an endovascular approach with stent placement in this indication.

Case: A 50-year-old woman, after jumping out of a window, arrived in coma with multiple organ lesions, haemorrhagic shock and initial haemodynamic instability.
