[Correlation between detrusor thickness, intravesical prostatic protrusion and maximum urinary flow in the monitoring of benign prostatic hyperplasia]. / Corrélation entre épaisseur du détrusor, index de protrusion prostatique et débit urinaire maximal dans le suivi de l'hypertrophie bénigne de la prostate.

INTRODUCTION: Detrusor thickness (DT) and intravesical prostatic protrusion (IPP) are closely related to bladder outlet obstruction. The aim of our study was to look for correlation between DT, IPP and maximum urinary flow (Qmax). METHODS: It is a prospective, observational study including men over fifty managed for benign prostatic hyperplasia. Low urinary tract symptoms were assessed with the International Prostatic Symptom Score (IPSS). Pelvic ultrasound was performed for all patients measuring prostatic volume, bladder volume, post- void residual, DT and IPP. Uroflowmetry was performed for all patients, Qmax was noted. Qmax equal or less than 15ml/s was considered pathologic. RESULTS: Sixty patients were included for our study. Strong negative correlation was noted between DT, IPP and Qmax (r=-0.59, r=-0.61 respectively). Patients with pathologic Qmax had higher DT and IPP than those with normal Qmax, the difference was significant (P<0.01). Threshold values predicting pathologic Qmax were 3mm for DT and 7mm for IPP. ROC analysis reveals for DT an AUC of 0.84 (95% CI 0.76-0.92) and for IPP an AUC of 0.88 (95% CI 0.80-0.97). CONCLUSION: Detrusor thickness and intravesical prostatic protrusion have strong negative correlation with Qmax. These parameters could be an alternative to Qmax measurement if uroflowmetry is unavailable. LEVEL OF EVIDENCE: Grade B.

Primary hydatid cyst of the kidney revealed by hydatiduria: A case report.

Hydatid disease is frequent in endemic regions especially in sheep farming areas. Kidneys are uncommonly affected (2%-4%). We report a case of right renal colic with hydatiduria revealing a primary renal hydatid cyst ruptured in the mid calyx proved by computed tomography scan and laboratory testing. A kidney sparing surgery was performed by excision of the protruding dome and suturing of the fistula without any postoperative complication. This case emphasizes on further studies to define a standard treatment modality for renal hydatidoses.

Bilateral ectopic pelvic kidney associated to left ureteropelvic junction syndrome: A case report.

Bilateral ectopic pelvic kidney is an exceptional finding and it may be associated rarely with other abnormalities of the kidney such as uretero-pelvic junction syndrome. We report a case of bilateral ectopic pelvic kidney revealed by left flanc pain with a left uretero-pelvic junction syndrome and a right ureteral duplication proved by computed tomography. A MAG3 renal scintigraphy was performed confirming the obstructive uretero-pelvic junction. An open left Anderson-Hynes pyeloplasty was performed without objectifying, preoperatively, any extrinsic compression without any postoperative complication. This case emphasizes on the possibility of the reconstructive management in such cases.
