Ultra-mini Percutaneous Nephrolithotomy (UM-PCNL) with a Semi-rigid Ureteroscope in Preschool Children: An Innovative Experience in Southern Iran.

Purpose: Percutaneous nephrolithotomy (PCNL) has undergone extensive modification to reduce complications. One of the recent advances in minimally invasive procedures is the advent of ultra-mini PCNL (UM-PCNL), which provides miniaturized access to the kidney. However, the specific instruments applied in UM-PCNL may not be found in centers with limited resources.

Intra-Examiner Reliability and Validity of Sagittal Cervical Spine Mensuration Methods Using Deep Convolutional Neural Networks.

The biomechanical analysis of spine and postural misalignments is important for surgical and non-surgical treatment of spinal pain. We investigated the examiner reliability of sagittal cervical alignment variables compared to the reliability and concurrent validity of computer vision algorithms used in the PostureRay software 2024. A retrospective database of 254 lateral cervical radiographs of patients between the ages of 11 and 86 is studied.

Objectives: Stuttering is a common problem at all ages that is required to be treated since childhood. Atomoxetine is currently used for the treatment of attention deficit hyperactivity disorder (ADHD). It can be effective for the treatment of stuttering due to its selective inhibition of norepinephrine reuptake and dopaminergic properties.

Minimal invasive percutaneous nephrolithotomy (Mini-PCNL) in children: Ultrasound versus fluoroscopic guidance.

Background: Miniaturization of endoscopic instruments in percutaneous nephrolithotomy (PCNL) allowed less invasive procedures with low complication rates, especially in children.

Outcome of Mini-Percutaneous Nephrolithotomy in Patients Under the Age of 18: An Experience With 112 Cases.

Renal calculi are becoming more common among children. Although, extracorporeal shock wave lithotripsy (ESWL) is the first choice in this age group, minimal invasive surgeries, such as percutaneous nephrolithotomy (PCNL), are indicated for some patients. Recently, PCNL devices have become smaller in size with acceptable efficacy and lower complications.

Percutaneous Nephrolithotomy During Early Pregnancy in Urgent Situations: Is It Feasible and Safe?

Purpose: Urolithiasis during pregnancy poses risks for mother and the fetus with specific challenges in diagnosis and management. We report our experience with urgent percutaneous nephrolithotomy (PCNL) in seven pregnant patients with symptomatic renal stone in early pregnancy.

Materials And Methods: Seven pregnant patients with symptomatic renal stones were reviewed.

Evaluation of hyoscine N-butyl bromide efficacy on the prevention of catheter-related bladder discomfort after transurethral resection of prostate: a randomized, double-blind control trial.

Background: Transurethral resection of prostate (TURP) is the most common treatment for benign prostatic hyperplasia (BPH). Urinary tract catheter is inserted post-operatively which results in catheter-related bladder discomfort (CRBD) in many patients. The purpose of this study was to assess the preventive effect of hyoscine N-butyl bromide on CRBD caused by a urinary tract catheter after TURP surgery in patients with BPH.

Pure ultrasonography-guided radiation-free percutaneous nephrolithotomy: report of 357 cases.

Purpose: To assess the safety and effectiveness of pure ultrasound-guided percutaneous nephrolithotomy.

Association of diet with prostate specific antigen and prostate volume.

Background: Prostate is an important male reproductive system gland and its disorders can affect men's quality of life and health. Prostatitis, benign prostatic hyperplasia (BPH), and prostate adenocarcinoma are major disorders that can be found in all men in different ages.

Objectives: The aim of this study was to investigate the association of diet with serum prostate specific antigen (PSA) level as well as prostate volume.

Percutaneous nephrolithotomy in solitary kidneys: experience with 412 cases from Southern Iran.

Some patients with nephrolithiasis who become candidates for percutaneous nephrolithotomy (PCNL) have a single kidney. This poses a challenge for the physician regarding the safety and efficacy of this procedure for these patients. This study has aimed to evaluate the safety and efficacy of PCNL in these patients.

Percutaneous nephrolithotomy: is distilled water as safe as saline for irrigation?

Purpose: To compare dilutional effect of distilled water with saline solution as an irrigation fluid in percutaneous nephrolithotomy (PCNL).

Materials And Methods: Three hundred twenty eight adult patients (191 men, 137 women) who were candidates for PCNL were randomly assigned into two groups (distilled water, n = 158, group 1; saline solution, n = 162, group 2). Stone size, operation time, irrigation fluid volume, blood hemoglobin level, urea nitrogen, creatinine, sodium and potassium levels were checked before and at 6 and 12 hours after operation.

A rare case of congenital entrapment of the left ureter in an iliac bone canal causing left side hydroureteronephrosis is reported. The patient represented a case of congenital ureteral entrapment in a reversed C-shaped iliac bone canal that was missed before his laparoscopy. The ureter also had a retro-iliac course.

Intrascrotal solitary neurofibroma: A case report and review of the literature.

Solitary Neurofibroma of the scrotum is an extremely rare benign tumor, particularly when it is not associated with neurofibromatosis type I. To the best of our knowledge, less than 10 cases have been reported in the English literature. Herein, we report a 52-year-old man with the diagnosis of scrotal solitary neurofibroma.

Laparoscopic nephrectomy for nonfunctioning kidneys is feasible after previous ipsilateral renal surgery: a prospective cohort trial.

Purpose: Previous renal surgery is a relative contraindication to laparoscopic nephrectomy because adhesion formation makes surgical dissection difficult. We determined whether previous surgery at the same anatomical site would affected the surgical outcome in patients who underwent transperitoneal laparoscopic nephrectomy.

Materials And Methods: During the study period 79 consecutive patients who underwent transperitoneal laparoscopic nephrectomy were evaluated prospectively.

Laparoscopic nephrolithotomy in a patient with crossed fused renal ectopia.

Background: A 32-year-old man was referred to a tertiary care center for stone management. The patient had initially presented to his primary physician 3 months earlier with right flank pain of 2 month's duration. Abdominopelvic ultrasonography and intravenous urography had revealed left-to-right crossed fused renal ectopia with a 25 mm opaque stone in the crossed kidney.
