3-dimensional ultrasound-guided percutaneous nephrolithotomy: total free versus partial fluoroscopy
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.
A large left renal calculus in the renal pelvis. Significant obstruction looking to the severe hydronephrosis. see more:https://www.ultrasound-images.com/renal-calculi/
Rationale: Mutations in the hepatocyte nuclear factor-1-beta (HNF1B) gene result in a very variable presentation, including maturity onset diabetes of the young (MODY), renal cysts, renal dysplasia, and autosomal dominant tubulointerstitial kidney disease (ADTKD), which is characterized by tubular damage, renal fibrosis, and progressive renal dysfunction. Patient concerns: A 22-year-old man came to the hospital presenting with hyperglycemia, hyperuricemia and elevated serum creatinine. His urine protein was within the normal range. The ultrasound examination revealed shrunken kidneys with renal cysts. The patient's mo...
Conclusions: US-guided MPCNL showed an excellent SFR and low complication rate in the management of pediatric patients with upper ureteral and renal stones. PMID: 32401098 [PubMed - as supplied by publisher]
CONCLUSION: PI-DJS during PCNL allowed for a reliable and stable reflux from the bladder into the renal pelvis to produce an artificial hydronephrosis without the formation of microbubbles, unlike conventional ureteral catheters. PMID: 32309876 [PubMed - as supplied by publisher]
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...
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...
Conclusions: Laparoscopic pyeloplasty and concomitant flexible renoscopy through lowermost trocar with basket extraction is a simple, attractive alternative for the simultaneous treatment of ureteropelvic junction obstruction presenting with coexisting nephrolithiasis. This method is useful and feasible, with minimal invasiveness and an early post-operative recovery.
CONCLUSION: The UProbe-2 ultrasound is safe and effective for puncture guidance during PCNL according to this initial study. It could provide a new and alternative choice for guidance of PCNL. However, more clinical trials especially randomized controlled trials should be performed. PMID: 29911509 [PubMed - as supplied by publisher]
CONCLUSION: Point-of-care ultrasound has modest diagnostic accuracy for diagnosing nephrolithiasis. The finding of moderate or severe hydronephrosis is highly specific for the presence of any stone, and the presence of any hydronephrosis is suggestive of a larger (>5mm) stone in those presenting with renal colic.
