Ability of ESWL nomograms to predict stone-free rate in children.

Introduction: We aimed to evaluate whether the pediatric extracorporeal shock wave lithotripsy (ESWL) nomograms can predict stone-free status in children effectively and whether they are applicable to our series. We hypothesize that two current nomograms predicting successful treatment with ESWL in pediatric patients are valid.

Study Design: We evaluated 415 renal units (children <18 years) with eligible data who received ESWL treatment for upper urinary tract stones.

Clinical results of shock wave lithotripsy treatment in elderly patients with kidney stones: Results of 1433 patients.

Objective: In this study, it was aimed to evaluate the efficacy and safety of SWL treatment in elderly patients with kidney stones.

Materials And Methods: Data from a total of 3024 patients who underwent SWL treatment for urinary tract stone disease in three centers of our university were evaluated retrospectively. A total of 1433 patients in the adult age group treated for single kidney stones were included in the study.

Time to stone clearance for ureteral stones treated with extracorporeal shock wave lithotripsy.

Objective: To evaluate the time to stone-free status after shock wave lithotripsy (SWL) for ureteral stones.

Methods: Medical records of 387 patients with ureteral stones who have been treated were retrospectively reviewed. Exclusion criteria for this analysis included nonopaque stones, prior ureteric surgery, multiple ureteral stones, anomalous kidneys or ureters, hydroureteronephrosis, infravesical obstruction, nonfunctioning kidney, inadequate follow-up, and treatment with calcium-channel blockers and alpha blockers.

Shock wave lithotripsy for distal ureteric stones: supine or prone.

Shock wave lithotripsy (SWL) has become the preferred first-line approach to most patients with symptomatic urolithiasis. The purpose of this study is to assess the ideal patient position during SWL for the treatment of distal ureter stones. A total of 342 patients included in this retrospective study.

Which factors may effect urinary leakage following percutaneous nephrolithotomy?

Objective: To evaluate the factors that may effect urinary leakage following percutaneous nephrolithotomy (PCNL).

Methods: Four hundred and thirty-three patients who underwent PCNL were reviewed retrospectively. The factors that may lead to leakage after surgery were analyzed as categorized into four groups according to individual variables (age, sex, body mass index); renal factors (previous surgery, extracorporeal shock wave lithotripsy history, presence of hydronephrosis); stone burden; and surgical features (access number, type of dilatation, presence of nephrostomy catheter).

The effects of hydronephrosis and stone burden on success rates of shockwave lithotripsy in pediatric population.

Objectives: To evaluate the efficacy of shockwave lithotripsy (SWL) with a third-generation SWL machine in the pediatric age group and to determine the effects of stone burden and the degree of hydronephrosis on the results.

Methods: Two hundred and sixty children with urinary system stones were treated with Siemens Lithostar Modularis Uro-Plus. The patients were divided into three groups according to stone burden (group 1: <100 mm(2); group 2: 101-200 mm(2); group 3: >200 mm(2)) and into four groups according to the degree of hydronephrosis (group 0: absent; group 1: mild; group 2: moderate; group 3: severe).

Do changes in a high serum prostate-specific antigen level and the free/total prostate-specific antigen ratio after antibiotic treatment rule out biopsy and the suspicion of cancer?

Objectives: To evaluate the impact of antibiotic treatment in patients with higher-than-normal prostate-specific antigen (PSA) levels in terms of changes both in total PSA and free/total (f/t) PSA ratios.

Materials And Methods: Serum PSA and f/t PSA changes after antibiotic treatment in 85 patients with normal digital rectal examination but elevated age-adjusted serum PSA levels were evaluated with relevance to biopsy results.

Results: Serum PSA levels decreased after antibiotic treatment in 47 of 85 patients.

VEGF, COX-2, and PCNA expression in renal cell carcinoma subtypes and their prognostic value.

Objective: To evaluate the prognostic value of new markers such as VEGF (vascular endothelial growth factor), COX-2 (cyclooxygenase-2), and PCNA (proliferating cell nuclear antigen) and review their differences in expression by histological subtype in patients with renal cell carcinoma (RCC).

Methods: About 99 patients who underwent radical (n = 79) or partial nephrectomy (n = 20) were included in this study. Histopathological specimens from the subjects were retrospectively analyzed immunohistochemically for the presence of VEGF, COX-2, or PCNA.

Efficacy and safety of a new-generation shockwave lithotripsy machine in the treatment of single renal or ureteral stones: Experience with 2670 patients.

Purpose: To review the treatment efficacy and to assess the complications encountered in patients with single renal or ureteral calculi managed with a new-generation SWL machine, the Siemens Lithostar Modularis Uro-Plus.

Patients And Methods: The stone location, size, minimum and maximum energy used, localization technique, number of shockwaves, fluoroscopy time, and number of sessions were reviewed for 2670 patients. The medical records were consulted to identify post-SWL secondary treatments in order to calculate the efficacy quotient (EQ).
