Comparison of supine and prone miniaturized percutaneous nephrolithotomy in the treatment of lower pole, middle pole and renal pelvic stones: A matched pair analysis
ABSTRACT Purpose We aimed to compare the outcomes of supine and prone miniaturized percutaneous nephrolithotomy (m-PNL) in the treatment of lower pole, middle pole and renal pelvic stones. Materials and Methods 54 patients who performed supine m-PNL between January 2017 and March 2018 and 498 patients who performed prone m-PNL between April 2015 and January 2018 were included in the study. Of the 498 patients, 108 matching 1: 2 in terms of age, gender, body mass index, American Association of Anesthesiology score, stone size, stone localization and hydronephrosis according to the supine m-PNL group were selected as prone m-PNL group. The patients with solitary kidney, upper pole stone, urinary system anomaly or skeletal malformation and pediatric patients (
CONCLUSIONThis study demonstrated an optimal approach for relieving upper urinary tract obstruction and acute infection in which percutaneous nephrostomy drainage is preferred for patients with severe pyonephrosis, large stones (>10 mm) with high-grade hydronephrosis, steinstrasse, or failure in retrograde ureteric stent placement, while retrograde ureteral catheterization using cystoscopy is suitable for patients diagnosed with small stones (≤10 mm) and low-grade hydronephrosis.

We report a case of small bowel herniation caused by the ureter in a woman who underwent radical hysterectomy for cervical cancer. Patient concerns: A 53-year-old woman presented with acute abdominal pain and vomiting and reported a history of radical hysterectomy for cervical cancer 6 years prior to presentation. Diagnoses: Computed tomography revealed segmental luminal dilatation of pelvic ileal loops, 2 transition zones with the beak sign in the left-sided pelvic cavity, and reduced enhancement of bowel loops. Hydronephrosis with abrupt luminal narrowing of the left distal ureter was also observed. Interventions:...
ConclusionThis video shows how deep urinary endometriosis can be performed laparoscopically. Mastering suturing is essential to avoid complications.
Pregnancy is associated with reactivation and transmission of latent polyomavirus to fetus. Polyomavirus is also known to cause ureteral stenosis and hydronephrosis.
Metastasis of prostate cancer (PCa) to renal pelvis is extremely rare. A 64-year-old man was hospitalized for increased prostate specific antigen (PSA) after radical prostatectomy. 68Ga-PSMA-11 PET/CT showed hydronephrosis caused by a mass in the left renal pelvis without significant uptake of PSMA tracer. The histopathology indicated metastatic PCa with a Gleason score of 5+5 but negative for prostate specific membrane antigen (PSMA) following nephroureterectomy. Although metastasis to renal pelvis is rare, the occurrence possibility could not be ignored when with hydronephrosis is found in prostate cancer patients.
Conclusion Inguinal herniation of the transplant ureter leading to ureteral obstruction is a rare, probably underreported, cause graft of dysfunction. Therefore, we advocate elective repair of inguinal or incisional hernias in renal transplant recipients. PMID: 31690216 [PubMed - as supplied by publisher]
ConclusionNLR and PLR are inversely associated with SSP of ureteral stones. In adjunct with other indicators, NLR and PLR are inflammatory markers that could be used in the clinical decision of ureteral stone management.
[Pelviureteric junction obstruction and crossing vessels: pro "vascular hitch"]. Aktuelle Urol. 2019 Nov 07;: Authors: Zahn K, Younsi NF, Stein R Abstract The vascular hitch procedure for pelviureteric junction obstruction caused by crossing lower-pole vessels is a controversial treatment option. Since this minimally-invasive technique has been introduced in patients with aberrant lower-pole vessels, multiple publications have reported successful short, intermediate and long-term outcomes. Success rates of > 90 % are similar to those of Anderson-Hynes pyeloplasty. In general, an ass...
We report a 36-year-old female who was referred to our hospital due to a 4-year history of dull pain on the left back. Diagnosis: X-ray and abdominal CT revealed a foreign body around the upper part of the left ureter with ureteral obstruction and hydronephrosis. Interventions: Laparoscopy was performed and a 3-cm sewing needle was removed successfully. Outcomes: After 6 months’ follow-up, the patient's ureteral obstruction and hydronephrosis were significantly reduced, and the double-J ureteral stent was removed. Lessons: This case indicated that ureteral obstruction and hydronephrosis caused by foreign ...
Conclusion: These results suggest that CsA can attenuate renal damage from severe hydronephrosis induced by renal pelvic perfusion in rabbits. It plays a protective role in the acute kidney injury process, possibly through increased MMP and mitochondrial changes. PMID: 31652042 [PubMed - in process]
