Objective To evaluate the diagnosis and treatment of urinary tract endometriosis.Methods Retrospective review of 10 female cases of urinary tract endometriosis was carried out. All cases age was from 28-49, and the average age was 39-year-old. The course of this disease was from 6 months to 3 years. Four of 10 cases were bladder endometriosis. The clinical presentations included the urgency, frequency, pain at micturition and lower abdomen pain during menstruation, gross hematuria coinciding with menstruation 1 case. B-ultrasound and CT showed the mass of bladder from 2. 0 -3.5 cm but were not specific. Four of 6 cases ureteral endometriosis were the left side and 2 cases were the right side. This clinical presentation included non-specific flank or abdomenal discomfort in 4 cases, intermittent gross hematuria in 1 case and 1 case renal hydronephrosis was found incidentally by B-ultrasound. B-ultrasound indicated unilateral upper urinary tract dilation and hydrops in all cases,with pyelic separation from 2.0-4.5 cm and ureteral separation from 1-2 cm. CT indicated stenosis of the lower ureter in 5 cases, ureter tumor in 1 case. Results All cases were treated surgically.Partial cystectomy were performed in 4 cases of bladder endometriosis, of which, 1 case bilateral oophorectomy and hysterectomy. Five cases were performed ureteral segmental resection, of which, 3 ureterocystostomy and 2 terminoterminal anastomosis. 1 case was performed radical nephrectomy and ureterectomy. Postoperative pathological findings confirmed the diagnosis of endometriosis. Postoperative oral hormone therapy was given to 9 cases for 6-12 months. All cases were followed for 12-60months. 2 cases ureteral endometriosis had recurrent hydronephrosis in 18-24 months. The 2 cases received ureteral stent and cured by oral hormone therapy or goserelin subcutaneous injection for 3 months. Conclusions Urinary tract endometriosis usually shows non-specific symptoms. The diagnosis can be missed on both clinical examination and preoperative work-up. Surgical treatment is effective and adjuvant hormone therapy is often recommended to prevent the recurrence.

Objective To investigate the therapeutic efficacy of castration with 125I brachtherapy in middle and late stage prostate cancer. Methods Sixty-six patients with prostate cancer from 2004 to 2009 were analyzed, 40 were at clinical stage C and 26 were at clinical stage D, 42 had a pathologic grade G2 and 24 had a pathologic grade G3. The first endocrinal therapy used was total androgen blockade (chemical castration and anti-androgen drugs). The therapeutic time was three months before bilateral orchidectomy and brachtherapy. A 3D radiotherapy planning system was used for brachtherapy with transrectal ultrasound-guided radioactive 125I seed uniform implantation. Follow-up endocrinal therapy was decided according to a monthly check of serum PSA (prostate specific antigen) levels. After six months, serum PSA, IPSS and volume of the prostate before and after treatment were compared. Results The operations were completed successfully in all cases. The mean number of 125I seeds implanted was 55. The mean follow-up was 10 to 62 months, with an average of 49 months. Serum PSA, IPSS and the volume of the prostate was reduced significantly six months after operation (P<0.05). Conclusions Castration with 125I brachtherapy is an effective approach in combination therapy for treating middle and late stage prostate cancer.

Objective To observe the efficacy of extensive decompression through transforaminal lumbar interbody fusion (TLIF) pathway combined with pedicle screw fixation on treating degenerative lumbar stenosis in the dderly.Methods Seventy-five elderly patients (28 males and 47 females) with degenerative lumbar stenosis were treated with extensive decompression through transforaminal pathway at our hospital from Jan.2007 to Aug.2010.The operation is through the TLIF pathway to resect part of the articular facet,and expose unilaterally the intervertebral vertebral foramen.Decompression of the vertebral canal was conducted by removing the disc.In the end,we performed posterolateral fixation with pedicle screw and placement of bone graft in posterolateral part of the lumbar or did the interbody fusion.JOA scores were obtained before and 1 day after operation and in 3 month follow-up consultation.The intervertebral height and bone fusion were observed by X ray.Results The follow-up period of the 75 patients was 6-36 months with an average of 12 months.There was significant difference (t =20.79,P ＜ 0.05 ;t =25.89,P ＜ 20.05) in JOA score between 3 month follow-up (21.08 ± 3.60) and preoperation (10.91 ± 2.23),between 1 d follow-up (22.72 ± 3.26) and preoperation (10.91 ±2.23),respectively.The rate of improvement was (88.6 ± 10.8)％,with 98％ of excellent or good in 3-month follow-up.Lumbar plane films showed neither instability or internal fixation loosening,breakage or distortion in follow-up consultation.There were 2 cases in whom Cage dislocation occurred without any neurological symptoms.Conclusion Extensive decompression through TLIF pathway combined with pedicle screw fixation is an efficacious method of treating degenerative lumbar stenosis in elderly patients.This method can retain the structure of lumbar posterior complex,reduce the risk of low back pain.It is a safe choice for treatment of degenerative lumbar stenosis in the elderly.

Objective To observe the clinical effect of percutaneous vertebroplasty f PVP)and percutaneous kyphoplasty(PKP)in the treatment of ostcoporotic vertebral compressive fracture. Methods Forty-two patients with osteoporotic vertebral compressive fractures were treated with PVP or PKP from August 2007 to July 2009.VAS and SF-36 scoring systems were employed to evaluate the Dain and quality of life.X-ray was used to evaluate the vertehral height restoration rate and the kyphosis correction rate.The bone cement leakage was determined based on the Chest X-ray. Results There was staitistical difference on PMMA leakage between PVP and PKP group.VAS and SF-36 scores at 2 wePks and 6months after operation were much better than those counted before operation in both PVP and PKP groups(P<0.05).The VAS and SF-36 scores at 6 months after operation showed no statistical difference in comparison with those before operation between PVP and PKP groups(P>0.05).At tWO weeks after operation,the height restoration rate of the fractured vertebral body(anterior and central column)in the PKP group waa better than that in the PVP group(P<0.05).The kyphotic correction rate in the PKP group was a little better than that in the PVP group(P>0.05).Conclusions In the treatment of osteoporotic vertebral compressive fracture,PVP and PKP have the similar effect on the pain relief,can refresh the height of the fractured vertebral body and correct the kyphotic angel of the fracture level to some extent.PVP has more PMMA leakage than PKP.

Objective To evaluate the occurrence and management of complications following ultrasound-guided minimally invasive percutaneous nephrolithotomy (MPCNL). MethodsFrom November 2003 to January 2011,2300 cases of ultrasound - guided MPCNL were performed for upper urinary tract stones in our department.Of these cases,renal calculi were found in 1305 cases,upper ureteral calculi in 322,renal and coexisting ureteral stones in 673. Results Among the 2300 cases of MPCNL,a total of 756 (32.9％) patients encountered complications.Of these cases,peel-away sheath placement failure occurred in 184 cases( 8.0％ ),in which six cases needed secondary surgery.Collecting system perforation occurred in 308 cases ( 13.4％ ),fever in 303 cases ( 13.2％ ),including septicemia in 20 cases (0.87％).The 20 septicemia patients received intensive antibiotic treatment and were successfully cured.Thrity-six patients required transfussions due to severe hemorrhaging ( 1.57％ ).Renal vein injury occurred in three cases (0.13％),for which these patients received intensive care therapy to provide haemostasis with a second procedure months later.There was extensive hemorrhage in 16 cases (0.70％) post-MPCNL,super-selective renal artery embolisation was performed in 12 cases and nephrectomy in 1 case.Pleural injury occurred in one case (0.04％) and pleural effusion in two cases (0.09％),all of which were cured with conservative therapy.There were no cases of abdominal organ injury.ConclusionsThe rate of ultrasound guided complications in MPCNL was lower than that of X-ray guided MPCNL in adjacent organ injury,but higher in complications related to the access ( such as:peel-away sheath placement failure,collecting system perforation),parenchymal bleeding and fever.Most complications (i.e.,bleeding,fever) could be managed conservatively or with minimally invasive procedures ( i.e.superselective renal embolisation,antibiotics treatment) when the complications were recognized early.Renal severe hemorrhage in operation,delayed hemorrhage and infection after MPCNL were several of the severe complications that required active prevention and cure measurement.

Objective To investigate the experience in management of the high risk benign prostatic hyperplasia (BPH) patients in order to improve the safety of the operation.Methods The high-risk factors of 115 patients with BPH who had been treated with transurethral resection of prostate (TURP) were analyzed.The blood pressure of hypertensive patients should be controlled below 140/90 mm Hg.The patients with myocardial infarction should be in stable condition for more than 6 months.Smoking cessation,oxygen inhalation,and pulmonary function training should be carried out during the perioperative period in patients with chronic obstructive pulmonary disease,correct expectoration methods and rational use of antibiotics were also needed to improve the maximum amount of pulmonary ventilation to more than 70％.The blood-glucose of diabetic patients should be controlled below 8 mmol/L by insulin.Catheter was indwelled in patients with chronic obstructive renal insufficiency for more than 2 weeks so that the blood Cr could be below 130 μmol/L.Anticoagulant therapy should stop at least 5 days before surgery.Patients were encouraged to have physical training early after surgery and to have ankle stretch movement when they recovered form anesthesia,and pressure cycle drive therapeutic apparatus were also used to prevent deep venous thrombosis.Results All the patients tolerated TURP safely.Operation time was 30 to 60 min,the weight of the resection prostate tissue was 12 to 37 g,blood loss was 80 to 150 ml,and catheterization time was 3 to 7 days.The overall incidence of complications was 1.7％.There were 2 cases with deep venous thrombosis,who recovered after anticoagulant therapy.There were no pulmonary infection,bleeding,TUR syndrome,and other complications.Conclusion Correct analysis and effective management of the perioperative risk factors in high-risk BPH patients treated with TURP can improve the safety of the operation and reduce the complications.

Objective To study the clinical and radiographic characteristics of complicated axis fractures combined with adjacent segment instability and explore reasonable surgical treatment strategy. Methods A retrospective study was performed on 21 patients with axis fractures treated from August 2003 to June 2009. There were 14 males and 7 females at mean age of 34 years. The treatment strategy was based on the fracture type and the stabilities of adjacent atlantoaxial joint and intervertebral C2/3.Treatment strategies included anterior C2/3 interbody discectomy and fusion, anterior cervical plate internal fixation, odontoid screw fixation, posterior C1-2 pedicle screw fixation, cervical lateral mass screw fixation or combined anteroposterior approach. Results All patients were immobilized in a hard collar for thee months and followed up for 6-36 months (average 12 months), which showed bony fusion and cervical stability, with no intraoperative surgery-related complications such as loosening, extrusion or breakage of fixation, vertebral artery injury, nerve damage, cerebrospinal fluid leakage or wound infection. Neurological recovery was observed in five patients. Conclusions For complicated atlas fractures, correct identification of fracture type and instability disturbance of adjacent atlantoaxial joint and C2/3 as well as active treatment can conduce to better effect.
