The drainage effect was evaluated by comparing the incidence of postoperative urinary leakage, urinoma, and/or hydrothorax development. Results: A total of 123 patients were assessed for eligibility, and 100 fulfilled the study requirements. The hemoglobin and hematocrit deficits were comparable. Significant hematuria and/or hematoma were recorded in 5 and 4 patients in groups 1 and 2, respectively. Blood transfusion was required in 5 and 6 patients in groups 1 and 2, respectively. One patient with chronic kidney disease in the tubeless group required abdominal exploration because of respiratory embarrassment and a large hematoma. Transient urinary leakage was recorded in 2 and 31 patients in groups 1 and 2, respectively (P <. 05). No urinoma developed. Hemothorax developed in 1 patient in the tubeless group with supracostal puncture. Postoperative pain was significantly less in the tubeless group. No statistically significant difference was found in the success rate, morbidity, or hospital stay between the 2 groups.
Nephrostomy Drawing of a nephrostomy tube in a human female ICD-9-CM 55. 02 MeSH D009403 [ edit on Wikidata] A nephrostomy is an artificial opening created between the kidney and the skin which allows for the urinary diversion directly from the upper part of the urinary system ( renal pelvis). An urostomy is a related procedure performed more distally along the urinary system to provide urinary diversion. Uses [ edit] A nephrostomy is performed whenever a blockage keeps urine from passing from the kidneys, through the ureter and into the urinary bladder. Without another way for urine to drain, pressure would rise within the urinary system and the kidneys would be damaged. The most common cause of blockage necessitating a nephrostomy is cancer, especially ovarian cancer and colon cancer. Nephrostomies may also be required to treat pyonephrosis, hydronephrosis and kidney stones.

All preoperatively placed PCN's were performed in emergency situations by interventional radiologists (IR). Complications were classified according to the Clavien-Dindo classification. We compared stone characteristics, operation time, complications, efficacy and PCN usability at surgery. Results Five hundred twenty-seven patients who were submitted to PCNL for renal stones were included in the study. In 73 patients (13. 9%) the PCNs were placed before the surgery. Patients and stone characteristics, mean operative time (p=0. 830), complications (p=0. 859) and stone-free rates (93. 0%) were similar between the groups. There was a trend toward higher complication rates in Group 1, but the difference was not statistically significant. Only 21 (29. 0%) of preoperatively placed PCNs were used during PCNL for establishing a tract. The reasons for not using PCN tract were: pelvic or infundibular insertion (30. 0%) and suboptimal anatomic location (70. 0%). Conclusions Preoperative emergency inserted PCNs by IR usage rates were low during PCNL.
The preservation of the nephrostomy tube after operation brings severe pain to the patients. We use a 1, 470 nm semiconductor laser to stop bleeding after the operation, which cannot reserve the nephrostomy tube, fully reflect its safety and effectiveness, and provide a new method for clinical practice. Methods: Forty-two patients with renal stones who came to our hospital from March 2016 to September 2019 were randomly divided into two groups: laser operation group (20 patients) and traditional operation group (22 patients). The stone removal rate, surgical effect, and postoperative complications were compared between the two groups. There was no significant difference in the stone clearance rate between the two groups at the 4th week after operation (P>0. 05). However, the incidence of postoperative infection, incision pain, and massive bleeding in the laser surgery group were lower than those in the traditional surgery group (P<0. However, there was no significant difference in urine extravasation and postoperative hematuria between the two groups (P>0.

Why Nephrostomy Tube Placement Is Performed Sometimes, the flow of urine from the kidneys to the ureters can become blocked. This can occur due to: A blood clot Injury to either the kidney or the ureter Kidney stones An infection A tumor What to Expect During Nephrostomy Tube Placement Nephrostomy tube placement generally takes less than an hour to complete. This procedure is performed using an intravenous sedative and a local anesthetic, meaning that patients will not be fully asleep, but will feel very relaxed and will experience no pain. Once the sedative and local anesthesia have been administered, the interventional radiologist positions the patients on their abdomen in order to access the kidney. The radiologist then uses real-time ultrasound imaging to locate the area of the kidney where the nephrostomy tube will be placed. Next, they'll carefully guide a needle through the skin and to the kidney before replacing it with a catheter or nephrostomy tube, and securing it with a disc to keep it in place.
How long the catheter stays in place depends on the reason for its insertion. In people with pelvic cancer or bladder cancer where the ureter is blocked by a tumor, the catheter will stay in place until the tumor is surgically removed. If the cancer is inoperable, the catheter may have to stay in place for the rest of the patient's life. Morbidity and mortality rates The mortality rate of nephrostomies is of the order of less than 0. 05% and the incidence of the specific complications listed above ranges between less than 0. 05% (hemorrhage, kidney arterial blocking, and loss of kidney tissue) to less than 1% (injury to surrounding organs and septicemia). Alternatives In the treatment of ureter stones, extracorporeal shock wave lithotripsy (ESWL) has been most widely performed and has become the preferred treatment for this condition. ESWL is a new technique that offers an alternative to surgery for patients with kidney or ureter stones. ESWL works by pulverizing the stones into sand-like particles that can be excreted with little or no pain.
Stones occur more frequently in men. The condition strikes most typically between the ages of 20 and 40. Once a person gets more than one stone, others are likely to develop. Upper tract tumors develop in the renal pelvis (tissue in the kidneys that collects urine) and in the ureters. These cancers account for less than 1% of cancers of the reproductive and urinary systems. Upper tract tumors are often associated with bladder cancer. Description First, the patient is given an anesthetic to numb the area where the catheter will be inserted. The doctor then inserts a needle into the kidney. There are several imaging technologies such as ultrasound and computed tomography (CT) that are used to help the doctor guide the needle into the correct place. Next, a fine guide wire follows the needle. The catheter, which is about the same diameter as IV (intravenous) tubing, follows the guide wire to its proper location. The catheter is then connected to a bag outside the body that collects the urine.
