In our experience, PCNU tube placement is a safe and effective method for managing intractable hematuria in the acute setting when more conservative treatment approaches have failed. Further, PCNU tube is a valuable palliative treatment option in end-of-life care. A single PCNU tube can effectively divert urine from both kid-

A single PCNU tube can effectively divert urine from both kidneys, requires only one procedure site and subsequently only one drain to manage. Compared to urethral catheters, which are susceptible to clot obstruction in the setting of ongoing severe hematuria, PCNU tube allows for adequate urine drainage without obvious obstructive ...

In patients with hematuria refractory to conventional management techniques, the placement of a PCNU tube allows for cessation of bleeding, successfully diverts urine with no immediate complications and is not subsequent to clot obstruction of the tube. The use of PCNU tube is a viable treatment in …

2022年4月15日 · Bilateral percutaneous nephrostomy tube exchange for nephroureteral catheters. INDICATION: __ year old female with cervical cancer and obstructive uropathy. Had bilateral PCN placed _____. Is in process of converting to internalization. PCNU to be placed at present time. DATE: OPERATORS:

Nephroureteral Tube/Stent (PCNU) - tube through skin often with pigtail in the renal pelvis but ending in the bladder. A “retrograde nephroureteral stent” instead uses the same tube as a nephrostomy tube for a patient with an ileal conduit but the tube passes through the urostomy ending in the renal pelvis.

2009年9月1日 · Bilateral percutaneous nephrostomy (PCN) tube changes to percutaneous nephroureteral catheter (PCNU). (A) Indwelling PCN tubes. (B) Contrast injection with bilateral distal ureteral strictures. (C) Left PCNU placement. (D) Right PCNU placement. Proximal loop being formed in the renal collecting system.

2012年9月1日 · In this study, we compared between the efficacy and complications of percutaneous nephrostomy (PCN) tubes and those of internal ureteral stents (e.g., double-J stents) used for relieving ureteral obstructions. A retrospective chart review was performed.

Nephroureteral stents including antegrade, retrograde, or internal (double-J) stents are routinely placed by interventional radiologists. The purpose of this review is to provide a detailed and comprehensive description of indications, contraindications, technique, and various technical challenges of these procedures.

2016年6月17日 · There are four types of percutaneous urinary drainage catheters: 1. Percutaneous nephrostomy (PCN) refers to an external drainage catheter, placed via a flank approach, positioned in the renal pelvis (Fig. 53.1A). 2.

2016年1月20日 · PCN tubes divert urine from the kidney into drainage bags, which are cumbersome to care for and potential sources of infection. In contrast, percutaneous nephroureteral (PCNU) tubes by allowing internal drainage can preclude the need for a …
