Percutaneous nephrostomy was applied in some other urologic diseases and the efficacy was evaluated. Percutaneous nephrostomy for percutaneous nephrolithotomy (PNL) was performed in patients with various renal, perinephric and bladder diseases (n=79). The tract establishment, operation duration and complications were observed and the efficacy was assessed. The results showed that the tracts were successfully established in 79 cases. The operation lasted 4-20 min. 12F-16F single tract was established in nephrohydrop patients and 16F-20F single or multiple tracts were established in patients with pyonephrosis, renal cortical abscess, renal cyst and perinephric abscess. During dilation, no leakage of liquor puris was noted. Establishment of 18F single tract was achieved in one urinoma patient. In two patients with foreign body in kidney, the foreign bodies were removed via established 14F single tract. 18F tracts were established in 2 patients with bladder contracture, which was followed by the placement of 16F balloon urethral catheter for drainage. No complications, such as massive bleeding, intestinal injury and spreading of infection took place in our series. All the patients were followed up for 2-12 months. No long-term complications such as dropping of drainage tube occurred. It is concluded that as a minimally invasive technique, percutaneous nephrostomy has the advantages of convenience, simplicity and causing less complications and can be used for various urologic diseases.

Objective To evaluate the safety and efficacy of transcatheter arterial embolization (TAE) combined with argon-helium cryoablation in treating small renal cancers. Methods During the period from February 2008 to July 2013, a total of 44 patients with small renal cancer were treated with TAE and argon-helium cryoablation at The Medical Imaging Department of Nanjing General Hospital of Nanjing Military Area Command. The renal function was reexamined one month after the treatment. Contrast-enhanced CT or MRI was performed in all patients within 1-3 months after the treatment. By using mRECIST, the therapeutic efficacy was evaluated. All patients were followed up for 12-46 months (mean 28 months). Results A total of 48 lesions in the 44 patients were treated with sequential therapy of TAE and argon-helium cryoablation. Of the 48 lesions, complete remission (CR) was achieved in 38, partial remission (PR) in 6 and stable disease (SD) in 4, the remission rate (CR+PR) was 91.7%. No severe complications occurred in all patients, except one who developed localized hemorrhage during the performance of argon-helium cryoablation, which was improved after symptomatic medication. The mean postoperative hospitalization time was 4 days. Three patients were lost to follow-up, one patient died of esophageal cancer-related complication. The remaining patients were survival during the follow-up period, among them recurrence occurred in five within 13-22 months after the treatment, and the sequential therapy of TAE and argon-helium cryoablation had to be carried out once more. Conclusion For the treatment of small renal cancers, the sequential therapy of TAE combined with argon-helium cryoablation is minimally-invasive, safe and effective, and TAE that is performed before argon-helium cryoablation can reduce the incidence of bleeding occurring in the freezing process. Therefore, this technique should be recommended in clinical practice.
