“…15 Predictive factors associated with surgical outcomes of these modalities have been reported to be total stone burden and location of stone burden. [2][3][4][5][6] Stone-free rates for SWL ranged from 45% to 99%, depending on stone location, burden, and composition. [2][3][4] Stone-free rate for PNL in a single session consisting of 180 patients was 51%, and upper pole stones and greater size have been associated with lower rates of attaining stone-free states.…”

“…1 However, surgical outcomes of these modalities widely vary depending on total stone burden, location of stone burden, stone composition, and anatomy of the collecting system. [2][3][4][5][6] In large or complex renal stones located in multiple calyces, it may be difficult to achieve complete stone clearance in a single session. Such cases may require multiple procedures or multiple access tracts during PNL, which increase the risk for significant complications such as renal parenchymal injury or massive hemorrhage.…”

Purpose: To evaluate surgical outcomes of laparoscopic pyelolithotomy (LP) in relation to stone distribution within the kidney. Methods: Between August 2008 and February 2012, 77 patients underwent LP as first-line treatment for renal stone(s). Cases were classified into four groups, depending on stone location: Group I (located in only renal pelvis), Group II (located only in renal calyx), Group III (located in renal pelvis and in one calyx), and Group IV (located in renal pelvis and in multiple calyces). Patient and stone characteristics, surgical outcomes, and complications were evaluated. Results: Sixty-seven (81.8%) cases were stone-free after LP for large renal stones. Stone-free rates in a single session significantly decreased with greater stone dispersion ( p < 0.001). Mean hospital stay in group IV was significantly longer than in other groups ( p = 0.038). However, there were no significant differences in mean operation times ( p = 0.214), mean change in serum hemoglobin ( p = 0.709), postoperative analgesics usages ( p = 0.153), and number of analgesics used on an as-needed basis ( p = 0.079). There were no complications of grade IIIb or of greater severity. One patient in group II received blood transfusion, and 1 in group III required percutaneous drainage due to perirenal urine collection. Conclusions: LP is an effective and safe modality for managing renal stones diseases. Distribution of stone burden, and total stone burden, is an important predictor of surgical outcome of LP in renal stone diseases.

“…Before the 70s, retained stones were removed surgically by means of large incisions in the skin. After that decade, the treatment of calculi came to be undertaken by extracorporeal shockwave lithotripsy (ESWL) (1), percutaneous nephrolithotripsy (PCNL) (2-4) and endoscopic ureterolithotripsy. Today PCNL is the gold standard treatment for renal stones bigger than 2cm (5).…”

ARTICLE INFO ______________________________________________________________ ______________________Purpose: We developed a stereotactic device to guide the puncture for percutaneous nephrolithotripsy, which uses the distance from the target calyx to its perpendicular point on skin (SCD) to calculate the needle´s entry angle. This study seeks to validate the use of measurements obtained by ultrasound (US) and computerized tomography (CT) for needle´s entry angle calculation and to study factors that may interfere in this procedure. Materials and Methods: Height, weight, abdominal circumference, CT of the urinary tract in dorsal decubitus (DD) and ventral decubitus (VD), and US of the kidneys in VD were obtained from thirty-five renal calculi patients. SCD obtained were compared and correlated with body-mass index (BMI). Results: BMI was 28.66 ± 4.6 Kg/m 2 . SCD on CT in DD was 8.40 ± 2.06cm, in VD was 8.32 ± 1.95cm, in US was 6.74 ± 1.68cm. SCD measured by US and CT were statistically different (p < 0.001), whereas between CT in DD and VD were not. SCD of the lower calyx presented moderate correlation with BMI. Conclusion: SCD obtained by CT in ventral and dorsal decubitus may be used for calculation of the needle´s entry angle. SCD obtained by US cannot be used. A rule for the correlation between BMI and the SCD could not be determined.

Introduction: Extracorporeal shock wave lithotripsy (ESWL) is a safe and effective treatment of upper urinary tract calculi. While serious side effects are rare, transient cardiac dysrhythmias (CD) may be associated with ESWL. The exact etiology of these events, which are often unpredictable, is poorly understood. Awareness of CD during ESWL and identification of risk factors for developing them could help clinicians predict and manage them safely and effectively. The current study examines selected variables to determine whether they may predispose individuals to developing CD during ESWL. Methods: We compared 16 patients who experienced CD during ESWL to 56 control patients. Cases and controls were compared with respect to several continuous and discrete variables, including age, pre-treatment heart rate, number of shocks received during treatment, energy setting of the lithotripter, gender, presence of a ureteric stent, previous ESWL and side being treated. Results: Cardiac dysrhythmias occurred more frequently in younger patients and in those being treated for right-sided stones. The other variables did not influence the likelihood of CD. All CD resolved promptly following conversion to electrocardiogram (ECG)-gating. Conclusion: Younger age and right-sided treatment predisposed individuals to developing CD during ESWL. Careful ECG monitoring should be performed during treatment. RésuméIntroduction : La lithotripsie extra-corporelle par ondes de choc (LECOC) est un traitement sûr et efficace pour les calculs des voies urinaires supérieures. Les effets secondaires graves sont rares, mais des dysrythmies cardiaques (DC) transitoires peuvent être associées à la LECOC. L'étiologie précise de ces manifestations souvent imprévisibles est mal établie. La reconnaissance d'une DC pendant la LECOC et des facteurs de risque de cette manifestation pourrait aider les cliniciens à en prédire la survenue et à traiter cette manifestation avec efficacité et en toute sécurité. L'étude présentée ici examine des variables sélectionnées pour déterminer si ces dernières peuvent prédisposer à la survenue d'une DC pendant une LECOC. Méthodologie : Nous avons comparé 16 patients ayant présenté une DC pendant une LECOC et 56 patients témoins. Les cas de DC et les témoins ont été comparés sur le plan de plusieurs variables continues et ponctuelles, dont l'âge, la fréquence cardiaque avant le traitement, le nombre d'ondes de choc reçues pendant le traitement, le niveau d'énergie établi pour le lithotriteur, le sexe, la présence d'une endoprothèse urétérale, le recours antérieur à une LECOC et le côté traité. Résultats : Les dysrythmies cardiaques ont été plus fréquentes chez les patients plus jeunes et les personnes traitées pour des calculs du côté droit. Les autres variables n'ont eu aucun effet sur la probabilité de survenue de DC. Toutes les DC se sont résorbées rapidement après conversion par synchronisation à l'électrocardiographie (ECG). Conclusion : Un âge moins avancé et un traitement du côté droit prédisposent les pat...
