DJ Stenting Surgery
DJ stent is the short “J’stent” shape for double. It is a small tube from the kidney to the urinary bladder, that is placed in the body. It’s sustained for about 6 weeks. The lower portion of the urinary bladder is shaped like a typical “J,” while the upper portion is like a mirror image. The shape helps hold the stent inside the body.
DJ Stents Used for,
- To facilitate the passage of small and medium sized stones in the Kidney to pass. With DJ stenting almost all the Kidney stones less than 7 mm and about half the stones of sizes 7 to 12 mm would pass by themselves if there is sufficient intake of water.
- As a precursor for breaking stones in the renal pelvis, upper or middle calyces.
- As a precautionary measure in retroperitoneal surgeries for example surgeries for cancer of the Uterus.
- For keeping the Ureters patent in conditions like retroperitoneal fibrosis. If Ureters are not patent they can cause Kidney failure.
- After breaking ureteric stone to help the fragments pass and to prevent stricture formation.
- After breaking Kidney stones to help the broken fragments to pass and prevent the broken fragments from blocking the ureter. The broken fragments can line up and form what is called Steinstrasse which means Stone Street.
- To aid pus from the Kidney to pass out easily into the bladder.
- After surgeries on the renal pelvis or ureter to prevent stricture formation.
- Special kinds of DJ stents are used after surgeries like endoscopic surgery for hydronephrosis.
