[Pyeloplasty: aesthetic benefit of lumboscopy].

Study Objective: To evaluate the aesthetic benefit of lumboscopy versus lumbotomy in a group of patients undergoing pyeloplasty.

Material And Method: A telephone survey was conducted in 103 people operated by pyeloplasty via lumboscopy or lumbotomy. The questions concerned the appearance of the scar (size, relief; visible or invisible), skin complications, satisfaction with the scar, postoperative pain, length of hospital stay and return to physical activity or work.

Efficiency of [(18)F]FDG PET in characterising renal cancer and detecting distant metastases: a comparison with CT.

The purpose of this study was to assess the efficiency of fluorine-18 fluoro-2-deoxyglucose (FDG) positron emission tomography (PET) in the characterisation and primary staging of suspicious renal masses, in comparison with computed tomography, the current standard imaging modality. Fifty-three FDG PET studies were performed within the framework of a prospective study: 35 for both characterisation and staging of a suspicious mass, and 18 for staging early after surgical removal of a renal cancer. In the characterisation of renal masses, a high rate of false negative results was observed, leading to a sensitivity, specificity and accuracy of 47%, 80% and 51% respectively, versus 97%, 0/5 and 83% respectively for CT.

[Urological manifestations of Behçet's disease].

Behçet's disease is a systemic disease most frequently presenting in the form of oro-genital ulcers. More rarely, other genital and bladder lesions, responsible for disorders of micturition, may also be observed. In these cases, urological management is necessary to prevent repercussions on the upper urinary tract.

Assessment of the intrinsic urethral sphincter component function in postprostatectomy urinary incontinence.

Postprostatectomy incontinence remains a disabling condition. Sphincter injury, detrusor instability, and decreased bladder compliance have been previously reported as major factors. The aim of this study was to evaluate the urethral sphincter intrinsic component, which may provide passive continence.

[Role of complementary tests in the management of colo-vesical fistulae].

Objective: Colo-vesical fistulas (CVF) are a complication of inflammatory or neoplastic diseases of the lesser pelvis. Although the clinical diagnosis is obvious in the presence of pneumaturia or faecaluria, a number of patients require complementary diagnostic and/or pretreatment investigations. The objective of this study was to analyse the management of these patients in order to define the place and cost-effectiveness of complementary investigations.

A study of the anatomic features of the duct of the urachus.

The urachus is an embryonic remnant resulting from involution of the allantoic duct and the ventral cloaca. Attaching the bladder dome to the umbilicus, this duct becomes progressively obliterated during fetal life. It may subsequently persist as different variants after birth, some regarded as normal, others as pathologic, due to incomplete closure.

[Treatment of colovesical fistula: predictive factors of the maintenance of long-term digestion continuity].

Aim Of The Study: Colovesical fistulas (CVF) may occur in inflammatory or tumoral pelvic diseases. The aim of this study was to analyze the surgical management of patients with a CVF in order to define predictive factors of good results and long term digestive continuity.

Patients And Methods: From 1989 to 1999, this retrospective study included 37 patients, 19 men and 18 women, mean age: 69 years (range 37-93 years).

[Hand-assisted laparoscopic bi-nephrectomy for refractory arterial hypertension in kidney transplantation].

Objective: The authors report their preliminary experience of a manually assisted laparoscopic bilateral nephrectomy technique for refractory hypertension in renal transplant recipients.

Material And Methods: Between April and May 1999, 2 laparoscopic bilateral nephrectomies were performed with manual assistance using the Hand-Port. One patient was operated 4 months before renal transplantation and the other was operated 13 months after renal transplantation.

Robotic assisted, laparoscopic pelvic lymph node dissection in humans.

Purpose: We evaluate the feasibility and efficacy of robotic assisted, laparoscopic pelvic lymph node dissection for locally advanced prostate cancer staging.

Materials And Methods: Robotic assisted, laparoscopic pelvic lymph node dissection was performed in 10 consecutive patients with mainly T3 M0 prostatic carcinoma (robotic group). Operative, postoperative and pathological parameters were compared with the results of the last 10 patients undergoing conventional, laparoscopic pelvic lymph node dissection performed with similar indications by the same operator (laparoscopy group).

[Biphasic sarcomatoid carcinoma of the prostate].

Sarcomatoid carcinoma of the prostate is a rare aggressive tumor, characterized by an intimate admixture of two malignant epithelial and sarcomatoid components. We report the case of a prostate tumour reputed to have a poor outcome, in a 59-year-old man. The radical prostatectomy specimen was completely involved.

[Kidney harvesting in living donors with manually assisted laparoscopy: technique and results].

Objective: To evaluate the feasibility and complications of manually assisted laparoscopic live donor kidney harvesting.

Material And Method: Since June 1999, all related live donor kidney harvests have been performed by manually assisted laparoscopy. The patient is placed in the lumbotomy position and an 8 cm midline periumbilical incision is made.

Type 1-primary cutaneous meningioma of the scalp.

Type 1-primary cutaneous meningioma is a rare and often clinically unsuspected lesion of the scalp, forehead or paravertebral region which occurs at birth or during childhood. The pathogenesis of these lesions still remains uncertain. Several authors have emphasized that type 1-cutaneous meningiomas are not real tumors but sequestrated meningoceles or heterotopic meningeal nodules of the skin.

Epididymitis in children: is further investigation necessary after the first episode?

Objective: The aim of this study was to evaluate the usefulness of investigating underlying urinary tract pathology after the first episode of acute epididymitis in children with no prior urological history, and also to assess the possible predictive factors of urological disease at the time of diagnosis.

Methods: Children with acute epididymitis were studied retrospectively over a period of 8 years. Diagnosis was made either using ultrasonography or surgical exploration.

[Intraurethral Macroplastic injections in the treatment of urinary incontinence after prostatic surgery].

Objectives: To evaluate the results and the place of a minimally invasive intraurethral injection technique designed to improve the efficacy of the urethral sphincter in urinary incontinence after prostatic surgery.

Materials And Methods: A prospective study of 26 Macroplastique injections performed in 15 patients with a mean age of 66.4 years (range: 54 to 78 years) was conducted over an 18-month period.

[Malignant neuroendocrine tumor of the bladder: an entity not to be unrecognized].

The authors report a case of primary malignant neuroendocrine bladder tumour. This rare bladder tumour presents the morphological and immunohistochemical characteristic common to all neuroendocrine tumours observed in other organs. The urologist must recognise this histological entity, which requires multidisciplinary management.

[Recurrent febrile infections of the urinary tract and diverticulum of the urachus].

The urachus can present a partial or complete obliteration defect. If the defect is situated in its vesical extremity, it then forms a diverticulum. The authors report a case of diverticulum of the urachus in a young adult, responsible for recurrent febrile urinary tract infections since the beginning of adolescence.
