BACKGROUND: Lithiasis during pregnancy can be a serious problem representing a danger to both the mother and the fetus. Surgical intervention is needed in approximately one-third of patients reporting pain despite analgesia and/or signs of persistent infection and obstruction, but there is a lack of consensus in the scientific literature as to the use of the most appropriate procedure to treat this condition. CASE PRESENTATION: We describe our experience in the treatment of a complicated reno-ureteral lithiasis in a 27-year-old patient in the first trimester of pregnancy...

A 54-year-old man was introduced to our hospital for follow-up examinations after renal transplantation. At the initial visit, a 25 mm renal transplant stone was noted, which had enlarged to 32 mm at an examination 1 year later. We first attempted transurethral lithotripsy (TUL), but failed due to ureteral stricture. However, we could completely remove the stone in 2 sessions of percutaneous nephrolithotripsy (PNL). The incidence of urinary lithiasis after renal transplantation ranges from 0.17-1.8%, for which PNL and TUL are frequently used...

INTRODUCTION: For small renal calculi (< 2 cm) the currently available treatment options include extracorporeal shockwave lithotripsy (ESWL), retrograde intrarenal surgery (RIRS) and standard/mini percutaneous nephrolithotomy (PNL). A new method, microperc, has therefore been developed, in which a smaller tract size and smaller instruments were used. AIM: To present our clinical experiences with micropercutaneous nephrolithotripsy (microperc) in the treatment of small renal calculi...

Percutaneous nephrolithotripsy (PCNL) is today gold standard for the management of complex urinary calculi. Over its lifespan this surgery has been subjected to multiple modifications and variants: for example, the anatomical positioning of the patient is still under controversy, especially the opposition amongst the prone and supine approaches, the two most common patient positions currently used for PCNL. Our objective was to review the literature and to discuss advantages and drawbacks from either technique...

The article describes the results of percutaneous nephrolithotomy (PCNL) in 49 urolithiasis patients with a solitary kidney. In 44 (89.8%) patients the calculi were located in the kidney, in 5 (10.2%) patients - in the upper third of the ureter. The calculi were single (18; 36.7%), multiple (14; 28.6%) or stag-horn (17; 34.7%). Efficiency of PCNL estimated immediately after surgery and at the end of the third month of observation was 75.5 and 93.9%, respectively. Stone size (p=0.594), the baseline state of urodynamics of the upper urinary tract (p=0...

BACKGROUND: Percutaneous nephrolithotripsy (PCNL) is one of the main interventional treatment modalities for large kidney stones (> 2 cm diameter). With the implementation of miniaturised techniques the indications for PCNL have been broadened to smaller stones. Especially for urologists without emphasis on endourology it is difficult to have an overview of the growing multitude of available systems and techniques. This article describes the currently available systems for percutaneous stone treatment with their peculiarities and indications...

In staghorn and multiple nephrolithiasis, method of choice for removing kidney stones is percutaneous nephrolithotripsy (PCNL). However, it may be accompanied by the leaving off of stones or fragments in pyelocaliceal system. The study was aimed to the evaluation of possibilities of the standard PCNL in terms of complete removal of staghorn and multiple kidney stones. Percutaneous nephrolithotripsy was made by a single access using standard method in 99 patients with staghorn and multiple kidney stones. The average age of the patients ranged from 9 to 61 (34...

A certain proportion of patients with initial Percutaneous nephrolithotripsy (PCNL) management require ancillary procedures to increase the stone-free rate. In this study, we aim to analyze the efficacy and safety of flexible ureteroscopy combined with holmium laser lithotripsy (F-UL) for treatment of residual calculi after PCNL by comparison with extracorporeal shockwave lithotripsy (SWL). Total of 96 patients with residual renal calculi (4 mm to 20 mm) after PCNL was enrolled from May 2010 to March 2013. They were randomly divided into two groups: US Group: patients were treated with F-UL; SWL Group: patients were treated with SWL...

Double pigtail (JJ) ureteral stents, are the most commonly used method of urinary diversion in the ureteral obstructions. Encrustations may occur as a result of prolonged exposure due to forgetting these stents in the body. Removing these materials might be an annoyance. Forty-four patients from three tertiary referral centres with forgotten JJ stents left in them between the years 2007 and 2014 were included in the study. Stents could not be removed by attempted cystoscopy. As an alternative approach, extracorporeal shock wave lithotripsy (ESWL) was the first choice since it is minimally invasive...
