The objective: evaluation of the effectiveness and safety of percutaneous nephrolithotripsy in patients in the supine position. Materials and methods. For the period 2017–2021, 521 mini-PNL were performed according to the standard technique, where in 458 (87,9%) cases the operation was performed in the patient’s prone position, and in 63 (12,1%) cases on the supine position (group 1). The control group (2 group) consisted of 70 patients, sporadically selected among 458 patients to whom PML performed in a standard prone position. Mini-PNL was performed under combined regional (spinal-epidural) anesthesia in 98,7% (514) cases, in 1,3% (7) under endotrachial anesthesia. Results. The average time of surgery was 41,1±11,4 minutes in the 1st group and 57,4±10,3 minutes in the 2nd group (р<0,05), due to the lack of need to revolutionize the patient on the abdomen. Statistically greater (p<0,05) of the ability to perform/ additional percutaneous access in patients in the supaine position. Infectious complications (9,5 vs. 7,1%; p>0,05), stone-free conditions (96,4 vs. 98,2%; p>0,05) and average hospital stays (2,3 vs. 2,2 days; p>0,05). None of the patients in both groups had complications higher than Clavien IIIa. When performing PNL in the supine position, in contrast to performing PNL on the prone position, there is always the possibility of using combined endoscopic methods. Where 3 (4,8%) patients underwent combined retro- and antegrade approaches for combination of nephrolithiasis with «wedged» calculi of the pyelourethral segment and in distal ureter, and retrograde laser endoureterotomy was performed in one (1,6%) patient. The limitation of our study includes a small sample size and a lack of group randomization. Conclusions. The patient’s position on the supine position, during the implementation of PNL, is a safe technique and can be a particularly attractive option for the category of patients with high anesthesiological risk; in the case of planned simultane (transurethral and percutaneous) interventions on the UMP; in patients who are obese or with severe deformityof the spine.

Aims: To analyze the cost effectiveness of integrating a stiff shaft glidewire (SSGW) in percutaneous nephrolithotripsy (PCNL) relative to standard technique (ST). This is prudent because healthcare providers are experiencing increased pressure to improve procedure-related cost containment. Methods: ST for PCNL at our institution involves a hydrophilic glidewire during initial percutaneous access and then two new stiff shaft wires. The SSGW is a hydrophilic wire used for initial access and the remainder of the procedure. We collected operating room (OR) costs for all primary, unilateral PCNL cases over a 5-month period during which ST for PCNL was used at a single institution with a single surgeon and compared with a 6-month period during which a SSGW was used. Mean costs for each period were then compared along with stone-free rates and complications. Results: We included 17 total cases in the ST group and 22 in the SSGW group. The average operating room supply cost for the ST group was $1937.32 and $1559.39 in the SSGW group. The net difference of $377.93 represents a nearly 20% decrease in cost. This difference was statistically significant ( p = 0.031). There was no difference in postoperative stone-free rates (82.4% versus 86.4%, p = 1.0, respectively) or complications (23.5% versus 13.6%, p = 0.677, respectively) between ST and SSGW groups. Conclusion: Transitioning to a SSGW has reduced OR supply cost by reducing the number of supplies required. The change in wire did not affect stone-free rates or complications.

Background. At present, the percutaneous nephrolithotripsy (PCNL) is performed both in supine and in prone position. The aim of this paper is to describe an innovative position during PCNL. Methods. We describe a supine position. The patient’s legs are slightly abducted at the hips. The thorax is laterally tilted (inclination 30°–35°) and kept in the right position by one or two gel pads placed between the scapula and the vertebrae. External genitalia can be accessed at any time, so that it is always possible to use flexible instruments in the upper urinary tract. We used this position for a period of 12 months to treat with PCNL 45 patients with renal lithiasis. Results. All the procedures were successfully completed without complications, using the position we are describing. The following are some of its benefits: an easier positioning of the patient; a better exposure of the flank for an easier access to the posterior renal calyces of the kidney; a lower risk of pressure injuries compared to positions foreseeing the use of knee crutches; the possibility of combined procedures (ECIRS) through the use of flexible instruments; and a good fluoroscopic visualization of the kidney not overlapped by the vertebrae. Conclusions. This position is effective, safe, easy, and quick to prepare and allows for combined anterograde/retrograde operations.

Symmetry Criterion

The invisibility criterion which is the standard technique for determining the nature of dislocations seen in the electron microscope can at times lead to erroneous results or at best cause confusion in many cases since the dislocation can still show a residual image if the term is non-zero, or if the edge and screw displacements are anisotropically coupled, or if the dislocation has a mixed character. The symmetry criterion discussed below can be used in conjunction with and in some cases supersede the invisibility criterion for obtaining a valid determination of the nature of the dislocation.The symmetry criterion is based upon the well-known fact that a dislocation, because of the symmetric nature of its displacement field, can show a symmetric image when the dislocation is correctly oriented with respect to the electron beam.
