Irreversible Renal Function Impairment Due to Silent Ureteral Stones.

Objective: To evaluate if renal function loss and hydronephrosis due to a silent ureteral stone might be reversed.

Materials And Methods: We prospectively selected patients with silent ureteral stones between January 2006 and January 2014. A silent case was considered if there were no specific or subjective symptoms related to the ureteral stone.

Percutaneous nephrolithotomy in obese patients: comparison between the prone and total supine position.

Background: Percutaneous nephrolithotomy (PCNL) can be performed in the prone or in the supine position. Comparisons between the two techniques in obese patients are rare in the current literature.

Methods: The records of obese patients (body mass index >30) who underwent PCNL in the prone or complete supine positions were reviewed.

Metabolic assessment of elderly men with urolithiasis.

Objective: To assess the presence of metabolic disorders in elderly men with urolithiasis.

Methods: We performed a case-control study. The inclusion criteria were as follows: (1) men older than 60 years of age and either (2) antecedent renal colic or an incidental diagnosis of urinary lithiasis after age 60 (case arm) or (3) no antecedent renal colic or incidental diagnosis of urolithiasis (control arm).

Management of chronic unilateral hematuria by ureterorenoscopy.

Background And Purpose: Chronic unilateral hematuria is characterized by intermittent or continuous gross hematuria that cannot be diagnosed using standard radiology and hematology methods. In the past, it was managed with partial or total nephrectomy. In the age of minimally invasive procedures, however, endoscopy has enabled more accurate diagnosis and management.

Laparoscopic dismembered pyeloplasty in 47 cases.

Purpose: To evaluate the results of a sequence of 47 laparoscopic Anderson-Hynes pyeloplasties for the treatment of patients with ureteropelvic junction obstruction, independently of the etiology.

Materials And Methods: Twenty male and 27 female patients diagnosed with ureteropelvic junction obstruction were treated by Anderson-Hynes transperitoneal laparoscopic dismembered pyeloplasty from April 2002 to January 2006. The age of the patients ranged from four to 75 years, with a mean age of 32.

Laparoscopic pyeloplasty in secondary obstruction.

Purpose: To evaluate the management of secondary ureteropelvic junction (UPJ) obstruction by laparoscopic pyeloplasty.

Materials And Methods: Thirteen patients with symptomatic secondary UPJ obstruction undergoing laparoscopic pyeloplasty were included. Eight patients had obstruction on the right side and five patients on the left.
