肾移植术后并发泌尿系移行细胞癌8例

随着肾移植术后长期存活患者的增加,并发泌尿系肿瘤的发生率有逐渐增加的趋势[1].我们于2000年12月至2005年8月共收治同种异体肾移植术后8例发生泌尿系移行细胞癌患者,现总结报告如下.     

B超引导下经皮肾镜碎石术治疗肾下盏结石效果观察

目的探讨B超引导下经皮肾镜碎石术(PCNL)治疗肾下盏结石的临床疗效。方法肾下盏结石患者45例,结石直径8～35 mm,按结石径线分为≤20 mm组(A组)18例,>20 cm组(B组)27例,均在B超引导下行PCNL。结果 45例手术均成功,其中一期碎石41例,二期碎石4例;术后泌尿系X线平片(KUB)发现4例结石残留,总无石率为91.1%,A组手术时间为(64.4±20.2)min,无石率为94.4%(17/18),B组分别为(90.7±22.9)min、88.9%(24/27),两组手术时间相比,P<0.05,两组无石率相比,P>0.05。术后发生持续血尿需输血者2例,高热3例,经相应处理后均恢复。A、B组并发症发生例数(分别为2、3例)无明显差异(P>0.05)。两组均无肾周血肿、尿外渗、血气胸、结肠穿孔、肝脾等重要脏器损伤及死亡病例。结论 B超引导下经皮肾镜碎石术治疗肾下盏结石具有成功率高、安全、创伤小等特点,疗效不受结石大小影响。

肾移植术后并发自体尿路上皮多器官癌六例的临床分析

Objective To analyze the etiology, clinical diagnosis and outcomes of 6 cases of multifocal urothelial carcinomas following transplantation. Methods A retrospective analysis was performed on 6 cases of multifocal urothelial carcinomas following renal transplantation in our center. Results Six patients were diagnosed as having multifocal urothelial carcinomas, including 1 case of related renal transplantation. Five cases were diagnosed by painless gross hematuria 2～48 months after renal transplantation, and I patient was diagnosed as having bladder tumors by B-uhrasound. All lesions happened un-simultaneously, from 1.5～16 months, and each case accepted operation 2～5 times. One case accepted radical cystectomy and cutaneous ureterostomy of the graft, and one accepted radical cystectomy, cutaneous ureterostomy of the graft and urethrectomy. All of 6 cases received OKT3 or Daclizumab as the induced-immunosuppressive therapy and tacrolimus or cyclosporine A + mycofenolate mofetil + steroid as the maintenance therapy. Intravesical chemotherapy started in all patients immediately after the surgery. All operations were successful and most patients got satisfactory results. Conclusions Kidney recipients have a higher rate of transitional cell carcinomas which are characterized by easy metastasis, and mostly have unsatisfactory prognosis. Kidney recipients with hematuria should be examined carefully with cystoscopy, retrograde pyelography and cystourethroscopy. A routine examination at regular intervals after transplantation is very important.

输尿管子宫内膜异位症的诊断与治疗(附九例报告)

目的:探讨输尿管子宫内膜异位症的诊断与治疗方法。方法:回顾性分析9例输尿管子宫内膜异位症患者的临床诊治资料。所有患者术前均行B超和静脉尿路造影(IVU)检查,1例行逆行尿路造影(RUG)。9例均行手术治疗,切除盆腔包块,1例行输尿管粘连松解术;8例行输尿管病变切除,其中7例行端端吻合术,1例因侵犯壁间段,行输尿管膀胱吻合术。皆留置D-J管。术后皮下注射抑那通,共3个月。结果:9例术后4周拔除D-J管。术后3个月复查症状消失,B超输尿管梗阻均解除,肾积水缓解。随访2年,未见复发。结论:应重视对输尿管子宫内膜异位症的早期诊断。输尿管子宫内膜异位症缺乏典型临床表现,诊断子宫内膜异位症的患者,应定期行泌尿B超检查。IVU、RUG或MRU,可进一步明确病变。治疗原则是解除输尿管梗阻,同时治疗盆腔子宫内膜异位症。
