Transurethral holmium laser resection for adult ureterocele / 中国基层医药

Objective To explore the curative effect and security of transurethral holmium laser resection for adult ureterocele.Methods 22 cases with adult ureterocele were retrospectively studied.Eight adult ureterocele cases were male and 14 cases were female.The mean age was 36.5 years (ranged from 20 to 67years).All of the patients were unilateral onset,15 cases on the left side and 7 cases on the right side.The mean course of the disease was 31 months (ranged from 15d to 12 years).The clinical presentations were varied.All 22 cases were treated by tran-surethral holmium laser resection.About one -third of cyst wall were left in order to avoid vesicoureteral reflux and hydronephrosis.Results All 22 cases succeeded uneventfully.The pathologic study confirmed that 22 cases were ure-terocele.The mean hospital stay was 8days (ranged from 6 to 12days).Mean follow -up time was 17 months (12 -26 months),while 2 cases were lost.All 20 cases urine alalysis was normal.Five patients showed no hydronephrosis, while 10 cases showed less hydronephrosis.Cystoscopy showed all 20 cases ureteral healing was smooth,and none showed recurrence of ureterocele.Voiding cystourethrography showed none of vesicoureteral reflux.Conclusion Transurethral holmium laser resection would be a good choice for adult ureterocele,because the treatment has the advantages of simple operation,low requirement of equipment,safety and reliability.Especially for the primary level hospital,transurethral holmium laser resection is worth further clinical promotion.

Application of biapenem in percutaneous nephrolithotripsy / 中国基层医药

ObjectiveTo evaluate the efficacy of biapenem in percutaneous nephrolithotripsy for the prevention and control infections.MethodsA retrospective study was accomplished.The clinical data of 68 patients with PCNL which used biapenem for prevention and control infection from Aug 2009 to Feb 2011 in the hospital of Hubei Provincial Corps of CAPF were collected,the treatment effect of biapenem in percutaneous nephrolithotripsy was evaluated.Results57 cases use the injection biapenem each 0.3g,2 times a day intravenously 7 to 14 days could effectively prevent postoperative infections in perioperative period;11 cases of urinary infection and systemic inflammatory response syndrome after pereutaneous nephrolithotripsy use injection biapenem each 0.3g,every 8-hour intravenously 7 to 14 days,were effective treatment of postoperative infections.ConclusionBiapenem was effective in the prevention of infection in percutaneous nephrolithotripsy.

The protective effect of rosiglitazone on renal injury of severe acute pancreatitis / 中华急诊医学杂志

ObjectiveTo investigate the effects of rosiglitazone, the agent of highly selective peroxisome proliferator-activated receptor-γ agonist, on the renal injury of rats with severe acute pancreatitis. MethodsFifty-four male Wistar rats were randomly (random number) divided into three groups : sham operation group ( SO group), severe acute pancreatitis group ( SAP group ) and rosiglitazone pretreatment group (ROSI group) . Severe acute pancreatitis model was induced by retrograde infusion of 5％ sodium taurocholate into the biliopancreatic duct. Rosiglitazone (6 mg/kg) dissolved in 10％ DMSO were injected into the femoral vein 30 minutes prior to the modeling. The solution of 10％ DMSO was given to rats of SO group and SAP group. Rats were sacrificed 3, 12 and 24 h after modeling. The levels of serum amylase, serum creatinine, urea nitrogen, urinary albumin, urinary lgG and αl-microglobulin were measured and analyzed statistically. Kidney tissue samples were stained respectively with hematoxylin and eosin for histopathological evaluation.Results The levels of serum amylase, serum creatinine, urea nitrogen, urinary albumin, urinary IgG and αl-microglobulin were significantly increased (P ＜ 0. 05 )after modeling, while lesser increases were found in ROSI group 12 h and 24 h after modeling (P ＜0. 05)compared with those in SAP group. ConclusionsRenal injury can be induced by severe acute pancreatitis,while Rosiglitazone protects rats from renal injury in the setting of severe acute panereatitis.

Transurethral resection for urethral recurrence after neobladder reconstruction in patients with bladder cancer / 中华泌尿外科杂志

Objective To explore the surgical treatment of urethral recurrence after neobladder reconstruction in patients with bladder cancer. Methods In 89 consecutive patients with radical cystectomy, 5 patients (5.6%) presented with a noninvasive urethral recurrence at a median of 18 months (range 9 to 32 months). All 5 patients were treated by transurethral resection and intraurethral instillation with hydroxycamptothecin used as initial therapy. Mean follow-up was 37 months (24 - 52 months). Results All the 5 patients survived after the treatment. There was no one showed recurrence or distant metastasis. All the 5 cases achieved continence. Conclusion Urethral preservation at initial therapy for incipient noninvasive urethral recurrence would be a good choice and could maintain the quality of life.
