CONCLUSIONS: The vmPCNL seems to be sustainable, safe and feasible for kidney stones treatment in the pediatric population. PMID: 33016029 [PubMed - as supplied by publisher]
We reported no relevant complications (Clavien–Dindo > 2); one patient had fever and was treated with antibiotics. The experimental in-vitro model demonstrated the efficacy of FVDES, allowing the removal of about 90% of fragments.Our study showed that FVDES is effective when used as a tool for retrieval of residual fragments at the end of f-URS. This technology could ensure a complete cleaning of the intrarenal collecting system and represent a safe alternative to basketing.
Strictures of the ureter may occur from iatrogenic injury or impacted kidney stones. Complications from ureteroscopy may result in ureteral stricture in 0,5 – 2% of patients (1). Many methods of surgical correction have been described. Long proximal ureteral strictures are generally treated by replacement of the ureter with a segment of ileum, which is associated with significant morbidity. New techniques are being described in order to minimize the m orbidity associated with classic approaches, such as ureteroplasty with buccal mucosa graft, but there are no published articles of ureteroplasty using a gonadal vein as a graft.
AbstractTo investigate the reliability of newly defined CT-related parameters and cardiovascular risk factors in groups adjusted for stone size and location to predict spontaneous stone passage (SP) of uncomplicated ureteral stones ≤ 10 mm. The data of 280 adult patients with solitary unilateral ureteral stones ≤ 10 mm in diameter in non-contrast computed tomography were prospectively recorded. All patients undergoing a four-week observation protocol with medical expulsive therapy using tamsulosin were divided i nto two groups according to SP or no SP. Demographic, clinical and ...
Conclusion: In conclusion, patients with a ureteral catheter associated with APN should be given close attention with regards to the above risk factors. Early removal of the catheter is the best policy for the prevention of APN. PMID: 32975161 [PubMed - as supplied by publisher]
Kidney stone disease can have a number of adverse effects on patients including quality of life. Studies assessing outcome measures in this area have largely been focused on objective assessments such as stone free rate. However, as part of the evolution to shift healthcare to a more patient centered position, patient-reported outcome measures have emerged as an improved tool to address this deficit. Key patient-reported outcome measures in Urology now include Ureteral Stent Symptom Questionnaire, Wisconsin Stone QoL Questionnaire, Cambridge Ureteric Stone PROM, Cambridge Renal Stone PROM, and Urinary Stones and Intervention Quality of Life.
AbstractThe aim of this work was to determine which part of a double-J ureteral stent (DJ stents) showed the highest tendency to crystal, calculi, and biofilm deposition after ureterorenoscopic-lithotripsy procedure (URS-L) to treat calcium oxalate stones. Additionally, the mechanical strength and the stiffness of DJ stents were evaluated before and after exposure to urine. Obtained results indicated that the proximal (renal pelvis) and distal (urinary bladder) part is the most susceptible for post-URS-L fragments and urea salt deposition. Both, the outer and inner surfaces of the DJ ureteral stents were completely covered...
CONCLUSIONS: Diabetic patients are under greater risk to develop postoperative UTI following URS. Those patients with UTI history and HbA1c level higher than 6.9% must be followed carefully. PMID: 32886078 [PubMed - as supplied by publisher]
CONCLUSION: Utilizing direct visual semi-rigid ureteroscopic dilation with a semi-ridged ureteroscope prior to flexible ureteroscopy leads to successful primary ureteroscopy for renal stone treatment in most patients. This technique is an effective, safe and possibly cost-effective method of obtaining ureteral access to facilitate primary URS for renal stone treatment. PMID: 32861259 [PubMed - in process]
Symptomatic nephrolithiasis affects less than 1% of all pregnancies but poses unique risks to both mother and fetus. Diagnostic imaging in this population is challenging due to physiologic changes of pregnancy and concerns regarding fetal ionizing radiation exposure. Ultrasound remains the imaging modality of choice. Most patients can be managed with expectant management, but percutaneous nephrostomy or ureteral stent placement are options if intervention is warranted. Growing evidence also supports the safety and efficacy of definitive stone treatment.
