ABSTRACT
OBJECTIVE@#To evaluate the therapeutic effect and safety of holmium:YAG laser lithotripsy for treating ureteral calculi combined with acute renal failure.@*METHODS@#Ureteroscopic holmium: YAG laser lithotripsy was used in 13 cases of ureteral calculi.@*RESULTS@#After the operation the serum Bun and Cr levels in the patients decreased to different degrees or returned to normal and the stone free rate was up to 92.3% (12/13).@*CONCLUSION@#The ureteroscopic holmium:YAG laser lithotripsy can be the first choice for the upper urinary tract obstruction associated with acute renal failure,due to its safety and efficiency. It can also deal with the double sites of ureteral diseases.

OBJECTIVE@#To determine the expression of Smad4 and TGF-beta1 in bladder transitional cell carcinoma (BTCC), and to understand the mechanism of invasion, angiogenesis, and metastasis of BTCC.@*METHODS@#The expressions of Smad4 and TGF-beta1 in samples of 42 human bladder carcinoma and 12 normal bladder mucosa tissues were determined with standard immunohistochemical analysis. We also analyzed the relationship among the expressions of Smad4 and TGF-beta1 and invasion, angiogenesis, and metastasis of BTCC, and the correlation between Smad4 and TGF-beta1.@*RESULTS@#The positive rate of Smad4 in BTCC was significantly lower than those in normal bladder mucosa tissues (33.3% vs 83.3%, P < 0.01). The expressions of Smad4 in poorly differentiated, invasive, recurrent, or with lymph node metastasis of BTCCs were lower than those in well differentiated, superficial, nonrecurrent, or without lymph node metastasis ones (P <0.05). The positive rate of TGF-beta1 in BTCC was significantly lower than that in normal bladder mucosa tissues (64.3% vs 100%, P <0.01), which was positively correlated to that of Smad4 (P = 0.000).@*CONCLUSION@#The expressions of Smad4 and TGF-beta1 in BTCC decrease with the increase in clinical stage, poor pathological grade, and the recurrence and metastasis of BTCC.

OBJECTIVE@#To evaluate the cause and treatment of dysuria post trans-urethral resection of prostate (TURP).@*METHODS@#The clinical data and the treatment of 22 cases of dysuria post TURP were analyzed retrospectively.@*RESULTS@#All cases including 3 cases of glandular and extraneous material residual, 5 cases of urethrostenosis, 7 cases of bladder neck contracture, and 7 cases of detrusor muscle weakness, were cured after the treatment.@*CONCLUSION@#The main causes of dysuria post TURP were glandular residual, urethrostenosis, bladder neck contracture, and detrusor muscle weakness. Correct preoperative diagnosis and treatment during/post operation are the key to the prevention of dysuria post TURP.

OBJECTIVE@#To evaluate the therapeutic effect of harnal and proscar in treating benign prostatic hyperplasia (BPH).@*METHODS@#Two hundreds and twenty-two patients with BPH were randomly assigned into 2 groups:harnal (0.2 mg/d) group (n = 112) and proscar (5 mg/d) group (n = 108). American Urologic Association Symptom Index (AUA-SI) scores, the maximal urinary flow rate (Qmax) and prostatic volume were analyzed in the 2 groups.@*RESULTS@#After 12 weeks of treatment, 54.5% of the harnal group improved in AUA-SI score; 54.6% of the proscar group improved in AUA-SI score; and there was no significant difference between the 2 groups (P > 0.05). After 24 weeks of treatment, the proscar group (79.6%) had a greater improvement in AUA-SI score than the harnal group (64.3%) (P < 0.05); Qmax in the 2 groups was significantly increased than that before the treatment, and it is proportional to the therapeutic time. The prostatic volume in 2 groups had no significant change.@*CONCLUSION@#Harnal and proscar can significantly improve BPH symptoms and the urinary flow rate. The therapeutic effect of harnal and proscar has their own characteristics.
