Objective　This study aims to provide an anatomic basis for surgeries accompanied with the pudendal nerve and some explanations about the formation of thepudendal nerve.　Methods　The pudendal nerve was dissected from its origin to end branches in 16 human cadavers. Its formation, shape, tract, branches and relationship with vessels were observed. The data related to the pudendal nerve were also measured.　Results　The formation of pudendal nerve is discrepant from what we acknowledged before. The trunk of pudendal nerve is formed by the anterior branches of S2, S3 and S4 with S4 being absent in some cases. In the descending course, the trunk of the pudendal nerve is combined with some fibers from the posterior femoral cutaneous nerve and the sciatic nerve in its course. The intricate shape of the pudendal nerve owes to its relation with the posterior femoral cutaneous nerve and the sciatic nerve, and the relations among its branches also contribute to that. The relationship with vessels varies during its course in the inferior border of piriformis and the pudendal canal. The branches of the pudendal are divided into the branches in the pelvis and the branches out of the pelvis. The distance from the pudendal nerve in the Alcock’s canal to the bottom of the ischial tuberosity’s anterior border is (25.47±3.18) mm in male and (26.38±2.56) mm in female. The distance from the pudendal nerve at the ischial spine to the skin is (75.67±8.37) mm in male and (76.89±9.48) mm in female.　Conclusion　The detailed dissection of the pudendal nerve can guide clinician in the surgeries associated with pudendal nerve in some degree.

Objective　To evaluate the feasibility of three-dimensional reconstruction of multi-slice CT in the anatomical relationships between intrarenal arteries and the kidney collecting system in pigs.Methods　Eighty-one pig kidneys were examined with MVCT. Each kidney was evaluated with three-dimensional reconstruction , from which MPR , MIP，VR of the renal artery and collecting system were documented. The anatomical relationships between intrarenal arteries and the kidney collecting system were observed.　Results　Three-dimensional images of all pig kidney could exactly show the anatomical relationships between the kidney arteries and collecting system. It was found that there was only 1 artery per kidney. The primary branch of this artery divided into two branches in 79 cases (97.53%) and three branches in 2 cases (2.47%). The two-branch artery divided into cranial and caudal branches in 72 cases (91.14%). In 7 cases (8.86%) the primary division of the two-branch artery was in a dorsal and ventral branches. In all cases 2 arteries (1 ventral and 1 dorsal) involved the cranial caliceal group. In the dorsal mid zone a dorsal artery originated from the cranial division of the renal artery, which was positioned in 48.15% of cases. The arterial supply related to the ventral mid zone of the kidney consisted of branches that coursed horizontally in the ventral surface of the renal pelvis in 82.72% of cases. The caudal division of the renal artery supplied the ventral and dorsal surfaces of the caudal caliceal group in 85.19% of cases, while in 14.81% a dorsal artery supplied its dorsal surface.　Conclusion　Three-dimensional reconstruction of multi-slice CT was an effective method in studying the anatomical relationships between the intrarenal arteries and kidney collecting system in pigs.

Objective　To explore the ectopic osteogenesis introducing ability of recombinant human bone morphogenetic protein-2/chitosan/dextran sulfate composite microspheres and recombinant human bone morphogenetic protein-2/chitosan composite microspheres on SD rats.　Method　36 SD rats were randomly divided into three groups, in which the quadriceps muscle bag model of the rats were established; the bags were implanted respectively with rhBMP-2(group A), CS/DS microspheres (group B), and rhBMP-2/CS/DS microspheres (group C). Hardness of the implanted regions tissuesat the 4th,8th,12th weekend were observed, and four rats were sacrificed in each group, from which the ectopic bone tissues were harvested. The bone formation situation of plantation areas were generally observed, and the heterotopic ossification organization tissues were scanned by micro-CT, and were three-dimensionally reconstructed by using the Mimics software；parameters such astissue bone volume fraction (BVF), trabecular thickness (Tb.Th), bone mineral density (BMD) were detected; Some heterotopic ossification organization tissues were taken for histological observation and analysis of ALP activity and calcium content.　Results　At the 4th weekend, tissues around implanted regions of each group had slightly harder texture, and there was no significant difference among the three groups; at the 8th and 12th weekend, hardness of tissues around implanted regions of each group increased significantly, and the group C had harder tissues formed than group A and B. At the 4th weekend, HE staining showed that the three groups had a small amount of bone tissue formation, but not obviously; the BVF, Tb.Th, BMD, ALP activity and calcium levels of B, C groups were significantly higher than group A; there were no statistically significance on the above indicators of group B and C. At the 8th and 12th weekend, gradually-increased and marture bone tissues could be seen in the three groups under HE staining. However,there were more mature ectopic bone tissues in group B and C than group A; And the bone tissues of group C were more mature than group B. Meanwhile, the BVF, Tb.Th, BMD, ALP activity and calcium levels of group B and C were significantly higher than group A, and the above-mentioned indicators of group C were higher than that of group B.　Conclusion　rhBMP-2/CS/DS microspheres have stronger ability of inducing ectopic bone than rhBMP-2/CS microspheres and single rhBMP-2, and it mayhave good prospects for applicationin bone tissue engineering.

Objective　To analyze stress transmission rule of spinal vertebral body - intervertebral disc with mathematical and physical principles; to analyze the correlation between stress transmission rule of spinal vertebral body - intervertebral disc and clinical pathology.  Methods  The transverse diameter (L) and sagittal diameter (H) of the upper and lower sections on each vertebral body of C2~S1 in 10 intact spinal specimens were measured. Similarity principle of geometry was used: the area changes of upper and lower sections of vertebral body/intervertebral disc could be expressed in mathematical equations S1/S2=(a*b)/(A*B) and S=π/4*L*H to analyze the structure law of upper and lower sections of vertebral bodies; According to the structure of the intervertebral disc, principle of hydrostatic pressure F1/F2=S1/S2 was used to analyze the law of intervertebral disc pressure change.   Results  With regard to the spinal vertebral body section structure, the area increased in a S-shaped curve from the lower section of C2 to lower section of L4. The section area decreased from the lower section of L4 to the upper section of S1. The transverse diameter and sagittal diameter of the vertebral body - intervertebral disc determined the section area of the vertebral body and pressure coefficient K, K=L*H.    Conclusion   The structure of spinal vertebral body-intervertebral disc itself determines the specific mechanical transmission and distribution characteristics of the spine; Establishment of mathematical equations to recognize the structure and mechanical transmission law of the spine can help more intuitively understand and observe spinal mechanical characteristics and patterns of clinical spinal lesions.

Objective　To evaluate the value of flexible ureteroscope (FURS) for management of renal calyceal diverticulum calculi with ultrasound guided punctureof diverticulum.　Methods　Combined with reviewing the relevant literature, we retrospectively analyzed the clinical data of 16 cases of diverticular calculi. From August 2014 to July 2015, 7 men and 9 women with an median age 48 years among them, 14 patients sustained symptomatic caliceal diverticulum calculi while 2 patients were symptoms free. Those patients were treated by FURS. FURS recognition of diverticulum ostium with ultrasound guided puncturing intodiverticular cavity in lateral lithotomy position was performed. After the needle entered diverticular cavity, saline-diluted methylthioninium chloride was injected or guidewires were inserted gently through needle sheaths. At the same time, the orifice or wall of the diverticular cavity was recognized under FURS. A 200-mm holmium laser fiber was used to incise the stenotic infundibulum or diverticular wall. Diverticular calculi was fragmented and washed out of the diverticulum.  Larger fragments were extracted with basket.　Results　Of the 16 cases, calyceal diverticulum necks leading to calyx were identified in 10 cases, and another 6 cases were not found but their locations were determined. The diverticular walls of the later 6 cases were incised with laser. The stone free rate, fragment success rate and symptom free rate was 75%（12/16）, 87.5%（14/16）and 100%（14/14）, respectively. Two cases underwent repeated procedure for the residual fragments, and the fragments were all cleared successfully after second surgery. Diverticula became disappeared or shrunk in 6 and 10 cases 3 months after the operation, respectively.    Conclusion　Flexible ureteroscope combined with the ultrasound guided puncture of diverticular cavity for management of caliceal diverticulum calculimay provide a safe and an effective option. Ultrasound guided needle puncture into calyceal diverticulum may facilitate flexible ureteroscopic treatment of calyceal diverticulum calculi.

Objective　To investigate clinical application of a unilateral opening bone cement injection device in percutaneous vertebral plasty(PVP).　Methods　Using a unilateral opening bone cement injection device, channels were established by the side of the pedicle, and under DSA perspective,low-viscosity vertebral bone cement was introduced into the channel. Continuous injection of bone cement and adjustment of the opening direction under DSA monitoring were performed for osteoporotic compression fractures in 25 cases (33 vertebral bodies). The surgical duration, leakage of bone cement and its complication were recorded; the distribution of bone cement in the vertebral body were observed by X-ray. 　Results　25 patients were followed up for 6~12 months. The average surgical duration was (27.75±5.29) min, each injection of bone cement was (3.8±0.92) ml, VAS score points were (7.12±0.78) preoperatively and (2.2±0.57) 3 d postoperatively, and (1.44±0.71) 12 month spostoperatively. Compared with those before operation significant differences could be detected (P<0.01). Timely termination of 4 cases of bone cement leakage under intraoperative DSA monitoring, 2 cases of leakage in the vertebral body and intervertebral space, and 2 cases of lateral vertebral leakage were observed; no leakage into spinal canal causing nerve and vascular complications, and no serious complications such as pulmonary embolism occurred.   Conclusions　Single side open bone cement injection devicecan effectively change the intraoperative dispersion direction of bone cement, effective control of further outward leakage of bone cement. By adjusting the opening direction, bilateral distribution of bone cement can be achieved through unilateral pedicle approach.
