retroperitoneoscopic nephropexy for symptomatic Nephroptosis
Surgical Endoscopy and Other Interventional Techniques, 2002Co-Authors: Shihchieh Chueh, Juton Hsieh, Jungchien Chen, Y L Young, Shyhchyan Chen, Y P TuAbstract:Background: Open nephropexy for Nephroptosis creates significant morbidity. We describe our technique for retroperitoneoscopic nephropexy and evaluate its efficacy. Methods: Twenty-five renal units in 23 patients with symptomatic Nephroptosis underwent retroperitoneoscopic nephropexy by suturing the posterior renal capsules and transfixing them to the back muscles. The diagnosis and postoperative assessment were made by typical symptoms (via patient questionnaire) and findings of intravenous urography (IVU) when the position was changed from supine to erect. Results: Mean operative time was 188 min (range, 90–330). Mean narcotic use was 15.6 mg morphine. Complete resolution of symptoms occurred in 84% (21/25) renal units; 12% (three of 25) achieved partial improvement (>75% decrease of preoperative symptoms). Follow-up IVU showed that 88% of patients had a renal descent of <2 cm on standing; the others had a descent of 2–4 cm. All of the five renal units with hydronephrosis resolved completely after the operation. Conclusions: This modified technique of retroperitoneoscopic nephropexy is a minimally invasive, feasible, and highly successful option for treating patients with symptomatic Nephroptosis.

simultaneous treatment of a renal stone and Nephroptosis with a single session of percutaneous nephrolithotomy and nephropexy a case report
臺灣泌尿科醫學會雜誌, 2006Co-Authors: Chenhsun Ho, Hongjeng Yu, Shihchieh ChuehAbstract:Urolithiasis is a common disease in Taiwan. [1] In most cases, both endourological surgery and extracorporeal shock wave lithotripsy (ESWL) are feasible interventions. [2] However, concomitant urologic conditions may complicate the management of urolithiasis, and necessitate additional procedures. We report a patient who presented with a right ureteropelvic junction stone and significant right Nephroptosis. We successfully treated the patient with percutaneous nephrolithotomy and percutaneous nephropexy in a single session.

post transplantation Nephroptosis causing recurrent episodes of acute renal failure and hypertension secondary to intermittent vascular torsion of intraperitoneal renal allograft
Journal of Surgical Case Reports, 2017Co-Authors: Austin R Dosch, Madeleine V Pahl, Uttam Reddy, Clarence E Foster, Hirohito IchiiAbstract:Nephroptosis is a rare complication in renal transplantation, but one with significant associated risk. Due to non-specific clinical features, there may be a substantial delay in diagnosis and loss of the transplanted kidney due to renal pedicle thrombosis. We present a case of post-transplantation Nephroptosis after simultaneous pancreas and kidney transplant, which resulted in accelerated hypertension and reversible acute kidney injury >1 year after transplantation. Prompt detection of this rare entity leading to expeditious surgical intervention is necessary to preserve viability of the renal allograft.

Nephroptosis in a young woman with joint laxity
Nature Reviews Nephrology, 2009Co-Authors: Barbara A. Clark, Amandeep SekhonAbstract:This article considers the case of a 25-year-old woman with a medical history notable for joint laxity and hypermobility syndrome. She had recurrent episodes of severe, right-sided abdominal and flank discomfort, intermittent gross hematuria, and sensation of a mass on her right side. Intravenous pyelography led to a diagnosis of Nephroptosis.

Nephroptosis in a young woman with joint laxity
Nature Reviews Nephrology, 2009Co-Authors: Barbara A. Clark, Amandeep SekhonAbstract:Background . A 25-year-old woman was evaluated repeatedly from 10 months following her first pregnancy and delivery for recurrent episodes of lower right quadrant abdominal pain, hematuria and a sensation of mass. Despite investigations by several physicians over a 7 month period no clear diagnosis had been made, but a psychosomatic disorder or possible periodic blocked bowel had been suggested, after which the patient requested a consultation with a nephrologist. Her history indicated joint laxity syndrome and a mitral valve prolapse. She was undergoing continuing evaluation for a possible rheumatic condition. Investigations . Full history, physical examination, and intravenous pyelography. Diagnosis . Nephroptosis of the right kidney. Intervention . Exercises were prescribed to strengthen her abdominal musculature and she was advised to wear an elastic abdominal corset during the daytime. The patient is currently considering surgical intervention. This article considers the case of a 25-year-old woman with a medical history notable for joint laxity and hypermobility syndrome. She had recurrent episodes of severe, right-sided abdominal and flank discomfort, intermittent gross hematuria, and sensation of a mass on her right side.

retroperitoneoscopic nephropexy for symptomatic Nephroptosis using a modified three point fixation technique
Urology, 2005Co-Authors: St Wyler, Tullio Sulser, Roberto Casella, D Hauri, A BachmannAbstract:Abstract Introduction Laparoscopy has been reported as a minimally invasive approach for performing nephropexy in patients with Nephroptosis. We evaluated our results after retroperitoneoscopic nephropexy using a modified three-point fixation technique. Technical Considerations Twelve women presenting with flank pain and radiologically documented Nephroptosis underwent retroperitoneoscopic nephropexy. After complete dissection of the perirenal fat from the kidney, three nonabsorbable (Ethibond-0) sutures were placed on the posterior renal capsule between the upper pole, middle part, and lower pole of the kidney and the psoas muscle. The average operative time was 91 minutes (range 50 to 180), and the mean estimated blood loss was less than 50 mL in all patients. Postoperative urography revealed complete resolution of Nephroptosis in all cases. On a comparative pain analog score patients had 84% improvement (range 0% to 100%). Nine patients had complete resolution of their pain, and two had improvement of 70% to 80%. One patient did not have any improvement. The mean follow-up time was 3.4 years (range 0.5 to 5.5). Conclusions Retroperitoneosopic nephropexy with a modified three-point fixation technique of the upper posterior pole, middle part, and lower pole of the kidney to the psoas muscle is a rapid and effective minimally invasive procedure for treating symptomatic Nephroptosis with excellent intermediate-term results.
