Intravenous misplacement of nephrostomy tube following percutaneous nephrolithotomy: Three new cases and review of seven cases in the literature.

PURPOSE: We investigated the characteristics and management of patients with intravenous misplacement of a nephrostomy tube. MATERIALS AND METHODS: Between July 2007 and July 2013, 4148 patients with urolithiasis underwent percutaneous nephrolithotomy (PCNL) in our hospital. Intravenous misplacement of a nephrostomy tube occurred in two of these patients. Another patient with intravenous misplacement of a nephrostomy tube, who underwent PCNL in another hospital, was transferred to our hospital. The data of the three patients were retrospectively analyzed. RESULTS: The incidence of intravenous misplacement of a nephrostomy tube following PCNL was 0.5% (2/4148) at our hospital. A solitary kidney was present in one of the three patients. The tip of tube was located into the inferior vena cava (IVC) in two patients and into the renal vein in one patient. All three patients were successfully managed with strict bed rest, intravenous antibiotics and one-step (one patient) or two-step (two patients) tube withdrawal under close monitoring. None of the patients underwent antithrombotic therapy. The original operations were performed successfully under close observation in two patients and changed to another operation in one patient. All patients were discharged uneventfully. CONCLUSIONS: The incidence of intravenous misplacement of a nephrostomy tube following PCNL is 0.5% at our hospital. Intravenous nephrostomy tube misplacement is an uncommon complication of PCNL. A solitary kidney may render patients susceptible to this complication. Most patients may be managed conservatively with strict bed rest, intravenous antibiotics and one-step or two-step tube withdrawal under close monitoring.

[Evaluation of 126 radical cystectomy with orthotopic ileal or sigmoidocolic neobladder].

OBJECTIVE: To evaluate the long-term clinical effects of orthotopic ileal or sigmoidocolic neobladder. METHODS: One hundred and twenty six patients with bladder cancer who underwent radical cystectomy and orthotopic ileal or sigmoidocolic neobladder from 1989 to 2001 were followed up, the clinical data was collected and analysed. Hautmann orthotopic ileal neobladder was performed on 84 cases and orthotopic sigmoidocolic neobladder was performed on 42 cases; Lymph node clearing during surgery was performed on 62 cases, chemotherapy and radiotherapy was performed on 64 cases after surgery. The continence and complications were compared between sigmoidocolic group and ileal group, the tumor recurrent rate and the 5-year survival rate were compared between lymphnode clearing group and chemoradical therapy group. RESULTS: Complete follow up was performed in 122 cases. Ureter broaden and urine backflow rate were higher in sigmoidocolic group than in ileal group (P < 0.05), nocturnal continence rate in sigmoidocolic group was higher than in ileal group (P < 0.05); Post-surgical tumor recurrent rate in lymphnode clearing group was lower than in chemoradical therapy group (P < 0.05), the 5-year survival rate in lymphnode clearing group was higher than in chemoradical therapy group (P < 0.05). The overall short-term complication rate was 15.9% (20/126), the overall long-term complication rate was 9.8% (12/122). CONCLUSION: The effects of orthotopic ileal or sigmoidocolic neobladder were satisfactory with low complication rate, lymphnode clearing during the surgery can increase the 5-year survival rate when compared with the chemoradical group.
