Laparoscopic transposition of lower pole crossing vessels in children with extrinsic pelvi-ureteric junction obstruction: a worthy alternative to dismembered pyeloplasty.

Laparoscopic transposition of lower pole crossing vessels in children with extrinsic pelvi-ureteric junction obstruction: a worthy alternative to dismembered pyeloplasty. J Biol Regul Homeost Agents. 2019 Sep-Oct;33(5 Suppl. 1):105-110 Authors: special issue: “Focus on pediatric nephrology”, Scuderi MG, Spampinato G, Milazzo G, Betta P, Fusco M, Arena S, Falsaperla M, Chimenz R, Di Benedetto V Abstract Pelviureteric junction obstruction (PUJO) due to intrinsic or extrinsic causes is a common problem in childhood. Extrinsic compression by a lower pole-crossing blood vessel can present symptomatically in older children. In these cases, laparoscopies Vascular Hitch can represent a valid alternative to pyeloplasty dismembered. We analyzed the data of 4 children affected by extrinsic PUJO treated at our institution with the laparoscopic Vascular Hitch procedure modified by Chapman. Surgical indications included presence of clinical symptoms, worsening of intermittent hydronephrosis, signs of obstruction on the MAG-3 scan, clear or suspected images of polar crossing vessels on CT scan or Uro-MRI. All procedures were completed laparoscopically. No complications occurred. Mean follow-up was 13 months with resolution of symptoms and PUJ obstruction and significant improvement of hydronephrosis in all cases. When blood vessels crossing lower pole represent the pure mechanical cause of UPJ obstruction the laparoscopic Vascular Hitch procedure represents ...

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.

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.

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...

[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 ofโ€Š>โ€Š90โ€Š% 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]
