Needle renal displacement technique for the percutaneous approach to the superior calix.
Lezrek M, Bazine K, Ammani A, Asseban M, Kassmaoui el H, Qarro A, Alami M, Beddouch A. Lezrek M, et al. J Endourol. 2011 Nov;25(11):1723-6. doi: 10.1089/end.2010.0721. Epub 2011 Sep 9. J Endourol. 2011. PMID: 21905848
We describe a new renal displacement technique using an 18-gauge needle to facilitate superior calix puncture and consequently to decrease intrathoracic morbidity. Initially, a lower or middle calix is punctured with an 18-gauge needle. Then, the proximal end of the …

Falahatkar S, Moghaddam KG, Kazemnezhad E, Enshaei A, Asadollahzade A, Farzan A, Damavand RS, Aval HB, Khodabakhsh S, Esmaeili S. Falahatkar S, et al. J Endourol. 2011 Dec;25(12):1831-6. doi: 10.1089/end.2011.0278. Epub 2011 Sep 9. J Endourol. 2011. PMID: 21905849
In lower calix access, mean operative time was less than upper calix access (P=0.022, significant) and higher than middle calix access (P=0.930, nonsignificant). CONCLUSIONS: BMI, stone burden, imaging for access, and calix for access were effective parameters on op …

Pediatric Percutaneous Nephrolithotomy-Experience of a Tertiary Care Center.
Yadav SS, Aggarwal SP, Mathur R, Sharma KK, Yadav RG, Tomar V, Teli RD, Jain D. Yadav SS, et al. J Endourol. 2017 Mar;31(3):246-254. doi: 10.1089/end.2015.0842. Epub 2017 Jan 16. J Endourol. 2017. PMID: 27960540
Puncture was subcostal in 87.6% cases with tract dilated as much as 24F. Pelvicaliceal system was most commonly accessed through middle calix (73.94%). Upper caliceal puncture (23.78%) was more frequently used in complete (82.35%) and partial staghorn (51%) stones. …

Comparative study of percutaneous access for staghorn calculi.
Netto NR Jr, Ikonomidis J, Ikari O, Claro JA. Netto NR Jr, et al. Urology. 2005 Apr;65(4):659-62; discussion 662-3. doi: 10.1016/j.urology.2004.10.081. Urology. 2005. PMID: 15833502
Of the 119 patients, 16 (13.4%) had upper pole access, 70 (58.8%) lower or middle calix access, and 33 (27.7%) multiple renal access. RESULTS: The stone-free rate was 80.0% for those in the lower/middle, 87.5% for those in the upper pole, and 84.8% for those in the …

Pyelocaliceal Distribution of Kidney Stones Used as an Outcome Predictor in Percutaneous Nephrolithotomy After Being Evaluated with Preoperative and Postoperative CT Scan.

With regard to pyelocaliceal stone distribution, we classified our patients in two groups that we called "no extra stone in middle calix" (NESMC) and "extra stone in middle calix" (ESMC), according to the difficulty in reaching the stones. ...The resul …
