The visual percutaneous nephrolithotomy versus the conventional percutaneous nephrolithotomy in treatment for renal stone.

CONCLUSIONS: We found that visual PCNL was a safe and efficacious treatment for renal stones that may be considered as an alternative to conventional PCNL, especially in patients with mild hydronephrosis. Further prospective randomized controlled trials are needed to confirm the results of this study . PMID: 31287255 [PubMed - as supplied by publisher]

Authors: Kaya C, Kaynak Y, Karabag A, Aykaç A Abstract BACKGROUND: Our aim was to detect the role of radiological abdominal fat parameters by tomography and stone density by plain X-ray on extracorporeal Shock Wave Lithotripsy (SWL) stone-free rate. METHODS: The patients who had undergone SWL for a single opaque renal stone

Publication date: Available online 13 January 2020Source: Urology Case ReportsAuthor(s): Meng-Tian Liang, Chao Wang, Fa Zhang, Feng-Hai ZhouAbstractA 48-year-old man was presented in the local hospitalized where he lived because of lower back pain one month ago. Then he came to our hospital for kidney stones on the right side within horseshoe kidneys and hydronephrosis diagnosed by imaging and abdominal ultrasound. After we proceeded single standard percutaneous nephrolithotomy with holmium laser combined EMS, his stones were totally removed with little intraoperative bleeding. No eventful post-operative complications occu...

ConclusionsOur findings show that fluoroscopy-free total ultrasound-guided PCNL represents an alternatively safe and efficient approach for the treatment of renal stones. Further study will be required to evaluate fluoroscopy-free TUPN in various clinical settings.

AbstractThe aim of this study was to determine whether the presence or degree of hydronephrosis (HN) affects the stone disintegration efficacy of shock wave lithotripsy (SWL). A comprehensive literature search using PubMed, Embase, Cochrane Library, and Web of Science was conducted to retrieve relevant studies. Risk ratios (RRs) and mean differences (MDs) with corresponding 95% confidence intervals (CIs) were calculated for comparisons of outcomes of interest. In total, seven comparative studies with 2033 patients were included. Overall results indicated no significant difference in stone-free rate (SFR) and retreatment ra...

We present the case of a 46-year-old man who underwent successful antegrade ureteroscopy for lithiasis in his allograft ureter. At a scheduled follow-up 15  years after transplantation, computed tomography (CT) detected a 12-mm renal stone in the renal pelvis of the transplanted kidney. During his follow-up, gross hematuria was seen; the stone moved to the ureter, causing hydronephrosis. Ultrasound and non-contrast CT revealed hydronephrosis and a 15- mm stone in the transplanted ureter. Considering the stone size, location, and the difficulty of the access to the anastomosed ureteral orifice, percutaneous ureteroscop...

AbstractThe purpose of the study was to investigate variables that may predict ureteral stone impaction and create a new model to predict more accurately stone impaction based on preoperative NCCT findings. Data of 238 patients who underwent URS were analyzed. Stone size, stone location, Hounsfield unit (HU) value of the stone, ureteral wall thickness (UWT) and grade of hydronephrosis were recorded. HU values of the ureter which are measured proximal and distal to the stone were recorded. Subsequently, we determined the factors that could predict the stone impaction in univariate and multivariate logistic regression analys...

Abdülkadir Kandemir, Mehmet Giray SönmezUrology Annals 2019 11(3):310-313 Ureteral catheters are frequently used in urology clinics for intrinsic or extrinsic pathologies which cause ureteral obstruction to provide urinary drainage from the kidney to the bladder. With the increase in stent use, an increase is observed in complications occurring due to ureteral stents in direct proportion with this increase, and ureteral double-J (DJ) stents forgotten in the urinary system are observed commonly in urological cases when the patients do not refer to a health institution in this condition and may cause severe proble...

AbstractTo create an easy risk stratification to recommend the optimal subset of patients with 2 –3 cm kidney stones to receive retrograde intrarenal surgery (RIRS) or mini-percutaneous nephrolithotomy (MPCNL). A retrospective patient cohort was reviewed and compared (RIRS,n = 147 and MPCNL,n = 129). Overall, RIRS group obtained a lower SFR (66% vs. 93.3%,p
