The Circle Nephrostomy Tube: An Attractive Nephrostomy Drainage System Following Complex Percutaneous Nephrolithotomy.

ABSTRACT: To describe our experience with the circle nephrostomy tube (NT) (Cook Medical), a drainage system uniquely designed for use after multiple-access percutaneous nephrolithotomy (PNL).A retrospective review of 1317 consecutive patients undergoing 1599 PNLs at IU Health Methodist Hospital was performed. All multiple access cases utilizing circle NTs were reviewed and analyzed. The method of insertion of circle NT was demonstrated.A total of 1843 accesses were obtained in 1599 renal units (RUs): 380 upper pole, 129 interpolar, and 1334 lower pole. Multiple accesses in this series were required in 282 RUs (17.6%). Following multiple-access PNL, circle NTs, Cope loop, and reentry Malecot NTs were inserted in 91 RUs (32.3%), 208 RUs (73.8%), and 31 RUs (11%), respectively. None of the patients who had circle NT experienced clogging, dislodgement, or obstruction of the tube. The cost of circle, Cope loop, and Malecot NTs are 121.73 USD, 95.20 USD, and 81 USD, respectively.Circle NTs are easy to insert, secure, cost-effective compared with inserting two NTs. Circle NTs provide excellent drainage and facilitate secondary procedures.

Project description:ObjectivesTo assess the outcomes of percutaneous nephrostomy in England for renal decompression, in the context of metastatic cancer.MethodsRetrospective observational study of all patients undergoing nephrostomy with a diagnosis of metastatic cancer from 2010 to 2019 in England, identified and followed up within Hospital Episode Statistics.The primary outcome measure was mortality (14-day and 30-day postprocedure). Secondary outcomes included subsequent chemotherapy or surgery and direct complications of nephrostomy.Results10 932 patients were identified: 58.0% were male, 51.0% were >70 years old and 57.7% had no relevant comorbidities (according to Charlson's criteria, other than cancer).1 in 15 patients died within 14 days of nephrostomy and 1 in 6 died within 30 days. Factors associated with higher 30-day mortality were the presence of comorbidities (Charlson score 1-4 (OR 1.27, 95% CI 1.08 to 1.50, p=0.003), score 5+ (OR 1.29, 95% CI 1.14 to 1.45), p<0.001)); inpatient nephrostomy (OR 3.76, 95% CI 2.75 to 5.14, p<0.001) and admitted under the care of specialities of internal medicine (OR 2.10, 95% CI 1.84 to 2.40, p<0.001), oncology (OR 1.80, 95% CI 1.51 to 2.15, p<0.001), gynaecology/gynaeoncology (OR 1.66, 95% CI 1.21 to 2.28, p=0.002) or general surgery (OR 1.62, 95% CI 1.32 to 1.98, p<0.001)), compared with urology.25.4% received subsequent chemotherapy. Receiving chemotherapy was associated with younger patients (eg, age 18-29 (OR 4.04, 95% CI 2.66 to 6.12, p<0.001) and age 30-39 (OR 3.07, 95% CI 2.37 to 3.97, p<0.001)) and under the care of oncology (OR 1.60, 95% CI 1.40 to 1.83, p<0.001) or gynaecology/gynaeoncology (OR 1.64, 95%CI 1.28 to 2.10, p<0.001) compared with urology.43.8% had subsequent abdominopelvic surgery. Not receiving surgery was associated with inpatient nephrostomy (OR 0.82, 95%CI 0.72 to 0.95,p=0.007): non-genitourinary cancers (eg, gynaecology/gynaeoncology cancer (OR 0.86, 95% CI 0.74 to 0.99, p=0.037)); and under the care of a non-surgical specialty (medicine (OR 0.69, 95% CI 0.63 to 0.77, p<0.001), oncology (OR 0.58, 95% CI 0.51 to 0.66, p<0.001)).24.5% of patients had at least one direct complication of nephrostomy: 12.5% required early exchange of nephrostomy, 8.1% had bleeding and 6.7% had pyelonephritis.ConclusionsThe decision to undertake nephrostomy in patients with poor prognosis cancer is complex and should be undertaken in a multidisciplinary team setting. Complication rates are high and minimal survival benefit is derived in many patients, especially in the context of emergency inpatient care.
