Procedures for Interventional uro radiological tests

Advances in Interventional Uroradiological testing has created a major shift in the field of image-guided interventions in urology. Though the traditional biopsy and drainage techniques are still used regularly used for treatment, image-based stone management and endovascular management of hematuria have developed more. Ablative procedures for renal and prostate cancer and prostate artery embolization for benign prostatic hypertrophy have emerged into accessible and practical alternative treatments. Many urologic problems that were once administered surgically are now efficiently achieved using minimally invasive image-guided techniques. It can be administered on a single day basis using only local anaesthesia or conscious sedation.

Here are some Interventional Uroradiological tests:

NEPHROSTOMY

A minimally invasive urinary diversion procedure, wherein, the urologist uses image guidance to manoeuvre a drainage tube which is inserted percutaneously into the renal collecting system.

A nephrostomy is usually used as a temporary urinary diversion technique to relieve obstruction and to help treat acute kidney injury or systemic sepsis. It is best to correct it with an early intervention particularly when the patient has a single functioning kidney to prevent progression to obstructive nephropathy.

When does one need a nephrostomy

One may require when:

● Urinary diversion caused by an obstruction (stone, tumour, clot). ● Urinary diversion to prevent a leak or fistula. ● Treatment of sepsis in case obstruction has led to infected. ● Access for antegrade ureteric stenting. ● Access for hybrid urological procedures (percutaneous nephrolithotomy [PCNL]).

Procedure Planning the treatment is crucial to avert avoidable complications. CT scans are done to aid in identifying the anatomy and to know where the bowel is in order to avoid injury during the procedure. The nephrostomy is performed in our hospital near you using a combination of ultrasound and fluoroscopic guidance. Ultrasound is used to determine the dilated target calyx in the kidney. Adjacent bowel and pleura can also be visualised in order to prevent injury. Once the calyx has been punctured, fluoroscopy is used to image the opacified collecting system. Using a basic Seldinger method over a guidewire, the tract is dilated and a drain inserted. Result Nephrostomy tubes are used not only for diversion of urine in an obstructed kidney; they also stipulate renal access for antegrade ureteric stenting and other urological procedures. Seeking treatment with uroradiology tests with NU Hospitals in Bangalore for a nephrostomy can provide long-term renal support. ANTEGRADE URETERIC STENT INSERTION Ureteric stenting is the process by which an indwelling endoluminal tube is inserted into the ureter to ensure drainage of urine to the urinary bladder. When does one need antegrade ureteric stent insertion

● In order to relieve obstruction ● To control ureteral patency in ureteric injuries or leak ● To manage ureteral patency for stone treatment

Procedure Planning the case is crucial to err from the path of avoidable complications. A CT scan is used to diagnose and understand the severity of the obstruction. Ureteric stenting may be performed as an initial procedure or alongside an ongoing nephrostomy. Following renal access, a guidewire and catheter are used to find the obstruction/stenosis and gain access into the urinary bladder (or conduit). The stent is then advanced over a stiff guidewire into the urinary bladder, lead by the careful withdrawal of the wire and the use of a pusher/suture system to ensure a pig-tail forms both within the bladder and the renal pelvis.

These are minimally invasive treatment strategies often have very little procedure-related morbidity. And as a dedicated nephro-urology hospital near you, our specialists perform nephrostogram to help relive urological issues. Specialists trained in the procedures are continuing to expand on the techniques and treatment styles for better results.
