AlM: To study the clinical effect of the application of microscopic pterygium resection combined with different concentration of mitomycin C ( MMC) .
METHODS:A total of 110 cases of pterygium patients (120 eyes) were randomly divided into control group (58 eyes) and observation group (62 eyes) according to the odd and even number method. The control group adopted the pterygium resection combined 0. 3mg/mL MMC, and the observation group was given pterygium resection combined 0. 2mg/mL MMC. The cure rate and the recurrence rate, eyesight before and after the treatment, two groups of cornea and sclera wound healing situation, the incidence of postoperative complications were compared.
RESULTS: The cure rate and recurrence rate of the control group was 84. 5% and 15. 5% respectively, and the observation group was 93. 6% and 6. 5% respectively, the differences were statistically significant (P<0. 05). There were statistical differences of vision of the two groups before and after treatment (P<0. 05), and there were no statistical differences of the two groups between the two groups after treatment (P>0. 05). The cornea, sclera, wound healing time of the observation group were less than the control group, and there were statistical differences between the two groups ( P < 0. 05 ). The incidence of complications was 13. 8% in the control group and 3. 2% in observation group, with statistically significant difference (P<0. 05).
CONCLUSlON: The application effect of microscopic pterygium resection combined with MMC is remarkable, and the joint of 0. 2mg/mL concentration of MMC is more safe and effective, and is worth popularizing in clinical application.

OBJECTIVETo assess the value of transrectal ultrasonography (TRUS) in the diagnosis of midline prostatic cysts.

METHODSWe retrospectively analyzed the TRUS manifestations of 87 cases of midline prostatic cysts.

RESULTSOf the total number, 33 cases were diagnosed as Müllerian duct cysts, 21 cases ejaculatory duct cysts and the other 33 cases undifferentiated midline prostatic cysts; 19 cases had dilated seminal vesicles, 19 seminal vesicle agenesis, 9 seminal vesiculitis and 5 dilation of the ejaculatory duct.

CONCLUSIONTRUS, convenient, sensitive, safe and non-invasive, is a desirable method for the diagnosis of midline prostatic cysts.

OBJECTIVETo investigate the testicular blood flow in patients with testicular microlithiasis (TM) and its correlation with the seminal profile in infertile men.

METHODSWe selected 88 infertile men and examined them by testicular color Doppler and routine seminal tests.

RESULTSTesticular microlithiasis was found in 19 (19.3%) of the patients, classic testicular microlithiasis (CTM) in 7 (8.0%), and limited testicular microlithiasis (LTM) in 10 (11.3%). No significant differences were observed in the age of onset, bilateral testicular volume, resistance index (RI) of bilateral testicular arteries, semen amount and the rate of teratospermia. The bilateral testicular peak systolic velocity (PSV), sperm count and sperm motility were significantly lower in the CTM than in the LTM group (P < 0.05), but showed no statistically significant difference between the LTM and the non-calcification group.

CONCLUSIONTM may be one of the causes of poor sperm function in infertile men.

OBJECTIVETo study the safety, effectiveness and feasibility of suprapubis-assisted umbilical laparoendoscopic mini-dual-site surgery (SAU-LEMDS) in the treatment of varicocele.

METHODSThis study included 80 varicocele patients aged 24 - 44 (mean 28.5 +/- 2.6) years, 25 cases of grade I, 45 cases of grade II and 10 cases of grade III, 58 cases in the left side, 6 in the right and 16 in both sides, and all with asthenospermia. The patients were treated by SAU-LEMDS under subarachnoid anesthesia combined with general anesthesia in a supine position with a head-down-feet-up slope of 15 degrees. Two 5 mm trocars were inserted bilaterally at the umbilical edge, one with a 5 mm 30 degrees laparoscope placed in it, and another into the abdominal cavity below the pubic hairline with a 5 mm laparoendoscopic clipper placed in it. The operation procedure was similar to that of standard laparoscopic ligation of spermatic veins, with reservation of the spermatic artery and double-ligation of spermatic veins. And the procedure was repeated for the contralateral lesion in the bilateral cases. Postoperative follow-up was conducted for the incidences of orchiatrophy and testicular hydrocele and changes of seminal parameters.

RESULTSAll the operations were successful, with the mean operation time of (10 +/- 5.0) min (range 8 to 25 min) for the unilateral cases and (18 +/- 6.5) min (range 15 to 30 min) for the bilateral cases, the mean blood loss of (1.5 +/- 0.5) ml (range 1 to 2 ml), and the mean postoperative hospital stay of (2 +/- 0.5) d (range 1.5 to 3 d). The patients were followed up for 6 -24 (12 +/- 2.5) months, which showed significant improvement in sperm motility as compared with the baseline ([28.53 +/- 5.21] vs [19.62 +/- 3.56]%, P < 0.05), with 28 cases (35.0%) restored to normal. Recurrence was found in 4 cases (5.0%). Testicular hydrocele occurred in 7 cases (8.75%), but orchiatrophy in none. The scars in the umbilicus and suprapubis were invisible because of the wrinkles and pubic hair.

CONCLUSIONSAU-LEMDS is safe, effective and feasible for the treatment of varicocele. It is superior to umbilical laparoendoscopic single-site surgery (U-LESS) for its less invasiveness, simpler operation, and better cosmetic appearance.

OBJECTIVETo explore the effects of the combined method of abdominal axial flap transposition and penile elongation for the treatment of the remnant penis.

METHODSFifty-two cases of the remnant penis treated with the combined method from 1984 April to February 2004 were analyzed retrospectively. Follow-up ranged from 0.5 to 20 years postoperatively.

RESULTSThe lengths (both in normal and erectile conditions) and the circumferences of the penis gained after operation were (5.6 +/- 1.4) cm, (6.8 +/- 2.5 cm and (6.9 +/- 2.3) cm respectively. The recovery rates of the sensory function were 94.2% and 100% in the glans (immediately and 3 months after operation) and 32.7%, 51.9% and 75% in the flap area (3, 6 and 12 months postoperatively). The two-point distinguishing sense in the glans and the flap area was (5.1 +/- 0.9) mm and(7.9 +/- 1.3) mm 5 years after operation. Early complications included distant flap necrosis (3 cases), disruption of the wound (2 cases), part necrosis of the skin graft in the abdominal wall (2 cases) and poor contours occurred in 4 cases in the later period because of the thickness of the flaps. All of them were corrected with satisfactory results.

CONCLUSIONThe combined method of abdominal axial flap transposition and penile elongation was recommendable for the treatment of the remnant penis because of its positive effects and less complications.

OBJECTIVETo evaluate the health-related quality of life and postdischarge long-term outcome after severe acute pancreatitis.

METHODSThe hospital records of patients with SAP discharged healthy from January 2003 to December 2003 were reviewed. The Rand 36-item Health Survey with accessory question was mailed to each patient. The means and deviations for each of eight scales scores of SF-36 were calculated, the study population scores were compared with general Chinese population; Univariate analysis was applied to determining the effects of variables such as age, sex, causes of disease, mode of treatment, frequency of surgery, financial burden, length of stay, chronic complications. Accessory questions were analyzed separately.

RESULTSThe means and deviations for each of eight scales (PF, RP, RE, BP, VT, MH, SF, GH) scores of SF-36 in SAP patients were 83 +/- 15, 62 +/- 42, 69 +/- 36, 80 +/- 15, 69 +/- 19, 72 +/- 15, 75 +/- 18, 65 +/- 18, compared with general people. Except RP and SF, the others were similar. In the ANOVA of Physical Component Summary, the three variables mode of treatment, financial burden and length of stay were included (P < 0.05), while in that of Mental Component Summary, the two variables of gender and financial burden were included (P < 0.05).

CONCLUSIONSThe health-related quality of life in SAP patients is similar to that of general people. Greater attention should be given to mode of treatment, length of stay and financial burden to improve quality of life.

OBJECTIVETo investigate the clinical and pathological characteristics, treatment and prognosis of peripheral primitive neuroectodermal tumor (PNET) of the urinary tract and reproductive system.

METHODSThe clinical data and pathological characteristics of a PNET patient was analyzed and relevant literature reviewed.

RESULTSThe diagnosis was established by pathological and immunohistochemical method. The patient underwent radical surgery, followed by chemotherapy.

CONCLUSIONPathology and immunohistochemistry help the diagnosis of PNET. For the treatment of the tumors in the early stage, surgery is the best choice, and for that in the late stage, it can be followed by chemotherapy. The PNET of the penis is a rare disease and evidence still lacks for the evaluation of its prognosis.

OBJECTIVE: To review the clinical data of pathological morphology, diagnosis, surgical treatment of cor triatriatum in 15 patients. METHODS: Fifteen patients with a mean age of (14.6+/-10.3) years (range from 6 months to 40 years) were performed operations under extracorporeal circulation. Fourteen of the patients had cor triatriatum sinister, and 1 had cor triatriatum dexter; 12 of the 15 patients had other cardiac abnormalities. The excision of the fibromuscular membrane was accomplished through a right atrial incision in all of the 14 cases, and the associated abnormalities were corrected at the same time. RESULTS: One patient died after the operation, and the other survivors had good outcome. CONCLUSION Operation is necessary if the diagnosis is clear. The patients generally have good prognosis. Surgical results of cor triatriatum depend on the complexity of associated defects and the adequacy of the repair.

OBJECTIVE: To summarize the experience of mitral vavuloplasty for mitral insufficiency in 53 patients. METHODS: Between January 2001 and September 2006,53 patients (31 males and 22 females) with mitral insufficiency underwent mitral valve repair at our hospital. The mean age was (23.8+/-10.4) years, and the mean weight was (43+/-12) kg,including 29 cases of mitral prolapse,17 congenital mitral insufficiency, 5 rheumatic mitral insufficiency,and 2 other etiology. All operations were performed under cardiopulmonary bypass,moderate hypothermia and under the surveillance of transesophagus echocardiography. RESULTS: There were 2 early postoperative deaths,and another patient failed to repair and received valve replacement afterward. Postoperative echocardiography indicated that mitral insufficiency was completely corrected in 42 patients, and residual mitral regurginitation in the other 8 patients. During the follow-up with mean period 13.8 months,41 patients revealed 28 in NYHA classI,13 in Class II. CONCLUSION Mitral valve repair should be the preferred modes of surgical correction for regurgitate mitral valves. With proper vavuloplasty technique, patients with selective mitral insufficiency patients may achieve satisfactory effect.
