ABSTRACT

Objective To determine the feasibility and safety of transprostatic utricle seminal vesiculoscopy in the treatment of hemospermia. Methods Totally 11 patients with hemospermia, mean age of (46.6 ± 3.5) years, ranging from 38 to 68 years, for 3 months admitted from September 2012 to August 2015 were enrolled, Their main manifestations were hemospermia. Painful ejaculation was observed in 7 patients, and perineal and testicular pain occured in 4 patients. They all underwent transprostatic utricle seminal vesiculoscopy, and then were followed up for 3 to 6 months. Results Ten patients were operated successfully, but 1 patient failed. The operation revealed that the causes of hemospermia were seminal vesiculitis in 8 cases, seminal vesiculitis accompanied with seminal calculi in 2 cases, and ejaculatory duct cyst in 1 case. Operation time was (29.2 ± 3.2) min ( ranging from 25 to 37 min) , and hospital stay was 2 d ( from 2 to 4 d). Hemospermia disappeared in 10 patients within 1 month of surgery, and hemospermia recurrence was observed in 1 patient within 6 months. The patient was treated with transprostatic utricle Holmium laser incision, then hemospermia was dispeared,Two cases of postoperative epididymitis were cured after one week of antibiotic treatment. Conclusions Seminal vesiculoscopy is a safe and effective to treat hemaospermia.

ABSTRACT

Objective To investigate the clinical feature , pathologic characteristics and prognosis of urothelial carcinoma of bladder with squamous differentiation . Methods From Jan.2010 to Jun.2013, the pathological and clinical data of 96 cases of urothelial carcinoma of bladder with or without squamous dif-ferentiation were compared .Of the group with squamous differentiation , there were 39 males and 9 females with a median age of 70 (29 to 87) years.44 cases presented with painless gross hematuria .4 cases presen-ted with finding of bladder tumors in annual physical examination .TURBT, partial cystectomy and radical cystectomy were performed in 25, 8 and 13 cases, respectively.In addition, one case was only underwent bi-lateral ureteral skin gastrostomy .The last one only performed cystoscopy .In accordance with sex , age, path-ological stage and classification and surgical approach , 48 controls were selected .For the other group , there were 40 males and 8 females with a median age of 68 (39 to 86) years.45 cases presented with painless gross hematuria.3 cases presented with finding bladder tumors by annual physical examination .TURBT, par-tial cystectomy and radical cystectomy were performed in 28, 7 and 13 cases, respectively.All patients with retaining bladder had postoperative intravesical instillation for one year .Some patients with or without bladder performed 3-6 cycles chemotherapy with the GC protocol . Results In squamous differentiation group , there were 1 (2.1%) pTa, 25 (52.1%) pT1, 17 (35.4%) pT2, 4 (8.3%) pT3 and 1 (2.1%) pT4 tumors. Whereas, 1 (2.1%) pTa, 28 (58.3%) pT1, 16 (33.3%) pT2, 2 (4.2%) pT3 and 1 (2.1%)pT4 tumors were selected in the control group .There were 2 (4.2%) cases with low grade and 46 (95.8%) cases with high grade carcinomain in both groups .Patients were followed up with a mean duration of 16 and 12 months in squamous differentiation and control group , respectively .In squamous differentiation group , eight recur-rences were recorded with a mean follow-up of 12 months.Of the 3 died patients, only one died from bladder cancer.In control group, seven recurrences were recorded with a mean follow-up of 22 months, and no pa-tient died.For patients with TURBT, 3 year recurrence rate of patients with squamous differentiation was 49.5%, while the control was 34.8%.The difference was statistically significant (P<0.05). Conclusions Urothelial carcinoma of bladder with squamous differentiation is at a high level of malignant and recurrence . The rate of myometrial invasion with squamous differentiation is higher than pure urothelial bladder cancer . Patients with squamous differentiation should be closely followed up .

ABSTRACT

Objective To discuss the effect of QGY/CDDP hepatoma lines multi-drug resistance (MDR) reversed by gene transfection of mdr1,mrp-ASODN+ultrasound contrast agent+ultrasound.Methods The QGY/CDDP cells were transfected by mdr1,mrp ASODN+ultrasound contrast agent+ultrasound irradiation respectively and detected of the various indicators:cell adhesion rate,cell sensitivity to cell drug-resistance,the mRNA expression of mdr1 and mrp gene,the expression of P-gp and MRP protein. Results After mdr1-ASODN transfection,the drug sensitivity and expression of P-gp,MRP protein of QGY/CDDP cells were smaller changes(P>0.05),and the rate of cells adherent and expression of resistance gene mRNA were obvious changes(P<0.05).After mrp-ASODN transfection,the cells adherent rate,the drug sensitivity,the expression of resistance gene mRNA and P-gp,MRP protein were obvious changes respectively(P<0.05),the experiment group(group 2')had bigger effects(P<0.05).Conclusions mdr1. mrp-ASODN+ultrasound contrast agent+ultrasound irradiation could safely partly reverse MDR of hepatoma cells,which is a potential new approach for gene therapy.
