Small bowel obstruction caused by secondary jejunal tumor from renal cell carcinoma: A case report.

Background: Secondary jejunal tumor from renal cell carcinoma (RCC) is extremely rare in clinical practice and is easily missed and misdiagnosed because of the low incidence and atypical symptoms.

Case Summary: A 38-year-old male patient was diagnosed pathologically with left RCC after radical nephrectomy in 2012. The patient then suffered multiple lung metastases 2 years later and was treated with oral sorafenib without progression for 6 years.

DDD score for renal tumor: An intuitive and comprehensive anatomical scoring system to access the outcomes of retroperitoneal laparoscopic partial nephrectomy.

Objective: To present a DDD scoring system in assessing the complexity and outcomes of retroperitoneoscopic nephron-sparing surgery for kidney tumor.

Methods: We retrospectively evaluated 232 patients who underwent retroperitoneoscopic nephron-sparing surgery between January 2013 and September 2017 for a renal tumor. Both the DDD score and RENAL score were used to classify the tumors.

[Ileal ureteric replacement for iatrogenic long segment ureteric injuries].

Objective: To investigate the efficacy of ileal ureteric replacement in the treatment of iatrogenic long segment ureteric injuries.

Methods: The hospital records of 9 cases with iatrogenic long segment ureteric injuries during Aug. 2010 to Sept.

[Complete transperitoneal laparoscopic nephroureterectomy for upper urinary tract urothelial carcinoma].

Objective: To discuss the surgical skills and clinical value of complete transperitoneal laparoscopic nephroureterectomy.

Methods: We collected and analyzed the clinical data of 25 patients (14 renal pelvic carcinoma and 11 carcinoma of ulreter, right side 15 and left side 10) who underwent complete transperitoneal laparoscopic nephroureterectomy for the upper urinary tract urothelial carcinoma (UUT-UC) in Peking University First Hospital from May 2010 to April 2011.

Results: All the operations were successfully done by one surgeon with standard 4 or 5 trocars technique.

[Comparison and clinical significance of different imageological methods in the detection of transitional carcinoma of upper urinary tract: analysis of 234 cases].

Objective: To determine the diagnostic value of multislice CT urography (MSCTU) in patients with transitional cell carcinoma (TCC) of upper urinary tract by comparing other imageology methods used.

Methods: Two hundred and thirty four cases of transitional cell carcinoma of upper urinary tract, in which 82 cases were diagnosed pathologically with pelvic carcinoma and 152 cases with ureteral carcinoma, between June 2004 and September 2006 in our institute were enrolled in a retrospective study. Most of them underwent urological ultrasound, intravenous urogram (IVU), retrograde pyelography and MSCTU.

[Effects of inhibiting nucleosomal binding protein 1 on proliferation of human prostate cancer cells].

Objective: To explore the role of nucleosomal binding protein 1 (NSBP1) in the proliferation of human hormone-dependent prostate cancer cells by inhibiting its mRNA expression.

Methods: Four well-designed short-hairpin RNA (shRNA) targeting NSBP1, including a negative control shRNA, were synthesized and inserted into the pSilencer 2.1-U6 neo plasmid.

[Expression of nucleosomal binding protein 1 in normal prostate benign prostate hyperplasia, and prostate cancer and significance thereof].

Objective: To investigate the expression of nucleosomal binding protein 1 (NSBP1) in normal prostate (NP), benign prostate hyperplasia (BPH), and prostate cancer (PCa) and significance thereof.

Methods: Western blotting was used to detect the expression of NSBP1 in 10 specimens of NP from voluntary donors who died of accidents, and 15 specimens of PCa resected during operation. Immunohistochemistry was used to detect the NSBP1 expression in 19 specimens of NP resected during complete cystectomy from patients with bladder carcinoma, and 26 specimens of BPH and 40 specimens of PCa, all resected during operation.

[Prediction of the stage of patients with prostate cancer by the combination of serum prostate specific antigen and Gleason score].

Objective: To explore the method of predicting the stage of prostate cancer with serum prostate-specific antigen (PSA) and pathological grade.

Methods: One hundred and eighty-seven patients were studied retrospectively with prostate cancer diagnosed by systemic biopsy in our hospital. The rank correlation analysis, rank sum test and stepwise discriminant multivariate analysis were used to assess the correlation of serum PSA level, ratio of free PSA to total PSA (FPSA/TPSA ratio) with Gleason score (GS) and stage.

[Homologous dermal acellular matrix graft for urethral reconstruction in man (report of 16 cases)].

Objective: To investigated the value of homologous dermal acellular matrix graft (AMG) for urethral reconstruction in man, and found an ideal replacement material to simplify the urethroplastic surgery.

Methods: 16 male patients, aged 18-46 (mean 26.5), with urethral diseases were treated with allograft of tissue engineering material AMG.
