THE EFFECT OF EPHEDRINE AND PLACEBO ON HEMODYNAMIC CHANGES ITS COMPLICATIONS IN PATIENTS UNDERGOING PERCUTANEOUS NEPHROLITHOTOMY WITH SPINAL ANESTHESIA

OBJECTIVES To present the chronological development of the different positions described for percutaneous nephrolithotomy (PCNL), in an attempt to identify the reasons for their development and to highlight their specific advantages and disadvantages. METHODS Previous reports were identified by a non-systematic search of Medline and Scopus. RESULTS The classic prone position for PCNL was fi...

OBJECTIVES Objective parameters in computed tomography (CT) scans that could predict calyceal access during percutaneous nephrolithotomy have not been evaluated. These parameters could improve access planning for percutaneous nephrolithotomy. We aimed to determine which parameters extracted from a preoperative multiplanar reconstructed CT could predict renal calyceal access during a percutaneou...

Percutaneous nephrolithotomy on staghorn calculi is challenging Objectives: for urologists because it is difficult to remove all of the stones. The purpose of this study was to evaluate the associated factors of stone-free rate after primary percutaneous nephrolithotomy on staghorn calculi in a large series of patients at a single, tertiary referral, endourologic stone center. We collected data...

BACKGROUND Paravertebral block is often used to provide postoperative analgesia after renal surgery. In this case-series report, we present our experience with 3 patients in whom percutaneous nephrolithotomy was performed successfully under ultrasound-guided 3-segment lumbar-thoracic paravertebral block. CASE SUMMARY Three patients were scheduled for percutaneous nephrolithotomy. All 3 patien...

Although percutaneous nephrolithotomy is minimally invasive, it is associated with several complications, including extravasation of fluid and urine, the need for a blood transfusion, and septicemia. However, little is known about pulmonary complications after this procedure. Therefore, we aimed to evaluate the risk factors for and outcomes of pulmonary complications after percutaneous nephroli...

collecting system. Early in one’s experience, a catheterized approach may be beneficial for maximizing successful access with minimal complications. Once a level of comfort with percutaneous anatomy is achieved, a noncatheterized approach may be a natural evolution to performing percutaneous nephrolithotomy. A larger randomized study would assist in determining the value of pre-procedure cathet...

PURPOSE The cost-effectiveness of shock wave lithotripsy monotherapy, percutaneous nephrolithotomy and combined sandwich therapy in the treatment of staghorn calculi was examined. MATERIALS AND METHODS The cost-effective index, which estimates the average cost of making 1 patient stone-free, was computed for the various treatment options. Data for effectiveness of each therapy were used as av...
