Percutaneous nephrolithotomy in previously operated patients: A prospective study.

Purpose: To determine the effect of previous renal stone surgery on result and complications of percutaneous nephrolithotomy (PCNL).

Materials And Methods: Total 300 patients were enrolled in the study. We enrolled 100 surgery-naive cases (those with no history of any renal surgery) as control and labeled them as Group A.

The effect of closure versus nonclosure of lingual mucosa graft harvest site on postoperative morbidity in augmentation urethroplasty: A comparative study.

Objectives: The objective of this study is to compare postoperative morbidity of closure versus nonclosure of the lingual mucosa graft (LMG) harvest site in augmentation urethroplasty.

Materials And Methods: From January 2015 to November 2016, a total of 42 patients who underwent LMG urethroplasty randomized in 2 groups. In Group 1, donor-harvesting site was left open while in Group 2, donor site was closed.

Assessment of factors affecting the spontaneous passage of lower ureteric calculus on the basis of lower ureteric calculus diameter, density, and plasma C- reactive protein level.

Introduction: The study aimed to evaluate the factors which affect the spontaneous passage of lower ureteric calculus on the basis of noncontrast computed tomography kidneys, ureters, and bladder (NCCT KUB) stone diameter, stone density, and plasma C-reactive protein (CRP) level.

Materials And Methods: We conducted a prospective study of 200 patients with lower ureteric calculus 5-10 mm in size, from October 2015 to December 2016. All patients underwent NCCT KUB region with a 5 mm axial and reformatted coronal section.

Technique for single-stage reconstruction of obliterative or near-obliterative long urethral strictures in circumcised patients.

Purpose: To report our initial experience with urethral reconstruction using a combined dorsal lingual mucosal graft (LMG) and ventral onlay preputial flap for long obliterative or near-obliterative strictures in circumcised patients.

Materials And Methods: This was a retrospective study of 10 patients from January 2015 to June 2017 with long obliterative or near-obliterative anterior urethral strictures and circumcised prepuces. All patients underwent a combined approach using a dorsally LMG and a narrow preputial onlay flap ventrally to create a 26-30 Fr.
