Kidney stones - urinary is a common disease and tends to increase in both men and women. Currently, there are many modern, minimally invasive methods applied in the treatment of kidney and urinary stones. However, each method has its own advantages and disadvantages, and the application object will also be different.
1. Less invasive method
1.1 Extracorporeal lithotripsy Extracorporeal lithotripsy is a technique that uses pulses or lasers from outside the body in the area with stones. Waves penetrate the surface of the body, propagate in the water, converge on the stone, the stone will be broken. Stones are pushed out of the body by drugs that treat stones.
Advantages:
Extracorporeal lithotripsy is preferred for kidney stones < 2cm, upper 1/3 ureter, then lower 1/3 ureteral stone. The average lithotripsy was 81% (50-99%).
Disadvantages:
However, extracorporeal lithotripsy also has certain disadvantages such as:
Ineffective lithotripsy for solid stones (calcium oxalate stones with 1 water molecule), cystin stones. For stones larger than 2 cm, the effect is poor, in many cases, it has to be re-sprayed 2-3 times. The rate of lithotripsy is about 27% (7.1% - 50%). When having to reapply 2 or more times is an inconvenience for the patient in terms of money, time and health. The stone fragments do not go away, there is calcium accumulation remaining, causing the stone to return to become larger and difficult to move.
1.2 Ureteroscopy Lithotripsy is a technique that uses a ureteroscope to go from the urethra, through the bladder and up the ureter to directly access the stone. Then use compressed air or laser energy to break up the stone and pump and pick up to get all the stones out. Includes two methods:
Ureteroscopy using rigid or semi-rigid bronchoscope: This method is preferred for ureteral stones in the lower third and middle third. Ureteroscopy using flexible bronchoscope: Dissolve upper third ureteral stones, kidney stones. Advantages:
Can disperse all types of gravel < 20mm in size, including coral gravel. Simple method, patients can be discharged after about 12-24 hours of follow-up.
Disadvantages:
Not applicable to patients with urethral stricture or urinary tract in the stage of inflammation, infection. Risk of complications: perforation of the ureter (due to laser burning in the wrong position or spreading), not being able to place the endoscope to reach the location of the stone... High cost of lithotripsy.
1.3 Laparoscopy This is a method used to remove ureteral or renal stones using an endoscope through the peritoneum or retroperitoneum. At first, the surgeons preferred to go intraperitoneally, but recently only operated by the retroperitoneal route to avoid having to go into the abdomen. Only applies to upper ureteral stones and pyelonephritis. However, with the development of laser lithotripsy ureteroscopy with semi-rigid or flexible bronchoscope, the indications of this method are increasingly narrow.
1.4 Percutaneous lithotripsy Percutaneous lithotripsy is a technique to create a small tunnel about 6-10 mm, this tunnel runs from the skin to the kidney or stone site. Then use a laser to break up the stone and suck out small stones and pebbles.
This method is often applied to cases of pyelonephritis and calyx, rarely applied to stones in the ureter close to the renal pelvis. This method is preferred for complicated stones associated with urinary tract malformations such as cervical stenosis or ureteral junction stenosis.
Advantages:
The whole stone can be removed after one intervention, the method is applicable even to large stones.
Cons:
The tunnel for the endoscope to penetrate into the stone site may become infected after surgery or the process of dissolution is prolonged, which may cause blood loss. There are scars left after surgery. This method is quite expensive, after surgery, you have to stay in the hospital for about 3-5 days.
2. Medical treatment
2.1 Medical treatment of stone removal The aim is to support the patient to pass stones. Apply to: Small gravel less than 7mm in diameter, smooth, oblong-shaped gravel; The stone has not yet caused complications; Stones are also more likely to move and expel the natural way; The urinary tract under the stone is wide enough.
2.2 Treatment of symptoms or complications This method applies to patients: There is no indication for medical treatment of stone removal; no indications or no conditions for surgery, using less traumatic methods such as: stones in the calyx, kidney stones that the patient has contraindications to surgery or less traumatic methods; Prepare the patient for surgical or minimally traumatic intervention.
