ABSTRACT
Objective To report the experience and results in comparing laparoscopic radical nephrectomy (LRN) and open radical nephrectomy (ORN) in the treatment of clinical T_2 stage renal cell carcinomas. Methods Between Feb. 2004 and Jul. 2007, 30 patients (12 females and 18 males with average age of 58.0±8.5 years, range 42-68 years) received LRN and 36 patients (16 females and 20 males with average age of 60.0±9. 0 years, range 52-70 years) received ORN. The average tumor sizes in the LRN and ORN groups were (8. 5±2.2)cm (range 7-12 cm) and (8. 8±2.1)cm (range 7-14 cm) respectively. Renal cell carcinoma was histopatologically confirmed in all the patients of these 2 groups after surgery. Results The operative time in the ORN group (130±27 min) was significantly shorter than that in the LRN group (176±23 min), P<0. 01. The estimated blood loss in the LRN group (200±80 ml) was also significantly less than that in the ORN group (380±185 ml) , P<0. 01. Patients in LRN group experienced significantly earlier bowel function recovery (P<0. 01) and shorter duration of drainage (P<0. 01) than those in the ORN group after operation. No severe perioperative complications occurred in all patients. The follow-up range was 6-27 months (average 15±2 months). During the follow-up, 2 patients in the LRN group developed lung metastasis. In the ORN group, 2 patients developed liver metastasis and 1 developed lung metastasis. Conclusion LRN has the advantages of minimal invasiveness and rapid postoperative recovery comparable to those of ORN, and it might be an alternative treatment option for the clinical T_2 stage renal cell carcinomas.
ABSTRACT
Objective To investigate the influence of transurethral plasmakinetic resection of the prostate(PKRP)on sexual function. Methods From January 2007 to December 2007.165 patients received PKRP,who had sexual active and completed the follow-up data forms before and after surgery.The average age of this cohort was 71 years(from 55 to 79 years).The average history of disease was 5.5(3-15)years while the average prostate volume 57(33-82)g,IPSS(26.4±2.6),quality of lire score(5.54±0.50),the maximum flow rate(7.04±4.10)ml/s,the average residual 120(55～250)ml.45 cases were complicated with urinary retention,and bladder stones 45 cases.15 cases with prostate stones.Their sexual function was assessed by the international index of erectile function,ejaculation function and sexual satisfaction before and 6 months after surgery by questionnaires,and compared the respective scores using SPSS14.0 and χ2 test. Results All of 165 patients,the IIEF-5 improved from(23.4±4.7)point to(24.1±4.9)point 6 months after operation(P>0.05),there was not significant.The abnormal ejaculation rate increased from 18.8%(31/165 patients)to 75.2%(124/165 patients)(P<0.001)after PKRP,respectively.The retrograde ejaculation rate increased from 11.6% (19/165 patients) to 64.2%(106/165 patients) after PKRP, respectively.There was a significant difference.128 patients (77.6 % ) and 132 patients (80.0 % ) were satisfied with their sexual active before and after 6 months PKRP, respectively. Conclusions The results of this study confirmed that PKRP has no negative influence on the quality of erections measured by IIEF-5.The loss of ejaculatory function has no influence on patients sexual active.
ABSTRACT
Castleman disease (CD) is an uncommon lymphoproliferative disorder and is especially rare in the retroperitoneum or perirenal area. We report the case of a 42-year-old woman in whom we found on routine physical examination a mass localized in the right abdomen without clinically important constitutional symptoms for 30 days. Abdominal ultrasound, magnetic resonance images and computed tomography scans revealed a solid mass localized just below the right kidney in the retroperitoneum. The patient subsequently underwent an exploratory laparotomy. Pathological examination revealed a right retroperitoneal mass of CD (hyaline vascular type). The patient completely recovered after surgery. Castleman disease is commonly misdiagnosed as malignant lymphoma, lymphadenitis or ectopic thymoma. So far, its diagnosis is mainly achieved via histopathological examination of surgically obtained tissue. After removal of the lesion, local CD has a good prognosis.
