91.7±46.2 mL, P=0.22). During the mean 3.8-month follow-up for the ICG group and the 6.2-month for the non-ICG group, there was a trend for more severe complications in the non-ICG group.

Visualizing intraureteral ICG under NIRF is useful in challenging UUTRs, allows for rapid ureteral identification and accurate real-time delineation of the ureteral stricture margins, and provides encouraging follow-up outcomes compared with those in the non-ICG group.

To evaluate and compare the natural history and growth kinetics of sporadic clear cell renal cell carcinoma (ccRCC) with those of ccRCC in von Hippel-Lindau disease (VHL).

Sixty patients in the sporadic group with 61 tumors and 15 patients in the VHL group with 30 tumors whom all underwent delayed surgery after at least 12 months of active surveillance (AS) were enrolled to conduct a retrospective cohort study. The growth rate was calculated, and the growth kinetics between the sporadic and VHL groups were compared. The patient and tumor characteristics were reviewed, and their correlation with growth rate was analyzed.

The mean growth rate of sporadic ccRCC was 0.91 cm/year (ranging from 0-4.74 cm/year) and that of VHL ccRCC was 0.47 cm/year (ranging from 0.04-1.89 cm/year). The growth rate of sporadic ccRCC showed a tendency of being faster than that of VHL ccRCC but did not reach statistical significance (P=0.07). The factors affecting the growth rate were different between the two groups. For VHL ccRCC, the only factor that correlated with growth rate was initial tumor diameter (P<0.001), but for sporadic ccRCC, the only factor was pathological nuclear grade (P<0.001).

The growth rate of VHL-associated ccRCC might be slower than that of sporadic ccRCC. Furthermore, we identified a disparity in growth kinetics between sporadic and VHL-associated ccRCC.

To compare the safety and validity of a suctioning semirigid ureteroscopic lithotomy (Sotn-URSL) and minimally percutaneous nephrolithotomy (mPCNL) in treating upper ureteral stone larger than 15 mm.

Between February 2018 and December 2019, 97 patients who had upper ureteral stone >15 mm were consecutively included in this study. Forty-six patients underwent Sotn-URSL and 51 underwent mPCNL by the same surgeon. The following parameters were retrospectively assessed patient and stone characteristics, surgical details, perioperative outcomes, and stone-free rates (SFRs).

No significant difference was observed in two groups for patient and stone characteristics, except that mPCNL group had a higher incidence of severe hydronephrosis (19.6%

41.2%, P=0.021). Sotn-URSL group was similar to mPCNL group in terms of the mean duration of surgery (50.5±5.9

52.9±8.0 min, P=0.106) and the SFR after 1 month (91.3%

98%, P=0.187). The hospital stay after surgery of Sotn-URSL group was significant shorter than mPCNL group (1.4±0.6

2.3±0.7 days, P<0.001), and postoperative complications in Sotn-URSL group was less, especially postoperative pain (P=0.044).

Both mPCNL and Sotn-URSL are suitable for upper ureteral stones with a diameter of >15 mm. Nevertheless, further well-designed studies with long-term follow-up are needed to confirmed the results.

Dense tumor-associated lymphocyte infiltration is linked to mismatch repair (MMR) deficiency in colorectal and endometrial cancer. MMR deficiency is of high clinical importance as MMR deficient cancers tend to react favorably to treatment with immune checkpoint inhibitors. Strong lymphocytic infiltration is a morphological hallmark of seminomas. We thus asked whether seminomas may exhibit MMR deficiency at relevant frequency.

To screen for tumors with MMR deficiency, protein expression of MLH1, PMS2, MSH2, and MSH6 was analyzed by immunohistochemistry (IHC) on a tissue microarray (TMA) containing 574 seminomas.

In total, 536 cases were evaluable resulting in 481 seminomas with unequivocally intact MMR protein expression. In 55 cancers, one or several IHC stains were equivocal and lacked detectable MMR protein in both tumor and stromal cells. Large section IHC analysis of all 55 equivocal cases demonstrated substantial staining issues due to improper fixation in 54 cases and identified one tumor with clear-cut MLH1 and PMS2 protein loss. This seminoma showed homogeneous loss of MLH1 and PMS2 in the entire tumor mass whereas minor adjacent foci of associated germ cell neoplasia in situ (GCNIS) were MMR intact. Polymerase chain reaction (PCR) analysis using the 5 microsatellite loci of the "Bethesda Panel" revealed instability in 1 of 4 interpretable loci ("MSI-low") and additional instability of the complex tetra-penta repeat locus MYCL1 in this tumor.

In summary, one single seminoma with MMR deficiency, characterized by protein loss of MLH1 and PMS2, was identified among 536 interpretable seminomas (0.19%). MMR deficiency is not a relevant determinant of lymphocyte influx in seminoma.

To present our experience of transposing the penis to the perineum, with penile-prostatic anastomotic urethroplasty, for the treatment of complex bulbo-membranous urethral strictures.

Between January 2002 and December 2018, 20 patients with long segment urethral strictures (mean 8.6 cm, range 7.5 to 11 cm) and scarred perineoscrotal skin underwent a procedure of transposition of the penis to the perineum and the penile urethra was anastomosed to the prostatic urethra. Before admission 20 patients had unsuccessful repairs (mean 4.5, range 2 to 12); five patients were associated urethrorectal fistula; 16 patients reported severe penile erectile dysfunction (PED) or no penile erectile at any time and four reported partial erections.

The mean follow-up period was 45.9 (range 12 to 131) months. Nineteen patients could void normally with a mean Qmax of 22.48 (range 15.6 to 31.4) mL/s. One patient developed postoperative urethral stenosis. After 1 to 10 years of the procedure, nine patients underwent the second procedure. Of the nine patients, four underwent straightening the penis and one-stage anterior urethral reconstruction using a penile circular fasciocutaneous skin flap, and five underwent straightening the penis and staged Johanson urethroplasty. Seven patients could void normally, one developed urethrocutaneous fistula and one developed urethral stenosis.

Transposition of the penis to the perineum with pendulous-prostatic anastomotic urethroplasty may be considered as a salvage option for patients with complex long segment posterior urethral strictures.

This study investigated a comfortable suture angle (CSA) with optimized trocar position for closing the defect during renorrhaphy in retroperitoneal laparoscopic partial nephrectomy (LPN). The feasibility, usefulness, and safety of achieving the CSA with modified trocar position were determined for different tumor types.

Two optimized trocar positions were introduced for different tumor types. A suture angle was based on the tumor plane of the superficial parenchyma defect and the line formed by the needle holder. Preliminary surgical simulations determined a CSA that combined the least suture time with the greatest ease of performance. Achieving the CSA was attempted during renorrhaphy of 106 enrolled patients undergoing retroperitoneal LPN. Patients' characteristics, operative features, and follow-up information were collected and analyzed.

For 89 (83.96%) patients, a CSA was successfully reached and parenchyma recovered. The remaining 17 patients were successfully sutured, but the attempt to achieve nfluence the approach to get a CSA.

Prostate cancer (PCa) is the second lethal heterogeneous cancer among males worldwide, and approximately 20% of PCa patients following radical prostatectomy (RP) will undergo biochemical recurrence (BCR). This study is aimed to identify the immune-related gene signature that can predict BCR in localized PCa following RP.

Expression profile of genes together with clinical parameters from The Cancer Genome Atlas (TCGA) and the Gene Expression Omnibus database (GEO) and the immune-related genes from the Molecular Signatures Database v4.0 were applied to construct and validate the gene signature. The Cox regression analyses were conducted to identify the candidate genes and establish the gene signature. To estimate the prognostic power of the risk score, the time-dependent receiver operating characteristic (ROC) analysis and Harrell's index of concordance (C-index) were utilized. We also established a nomogram to forecast the probability of patients' survival.

A total of 268 patients from the TCGA and 77 pagnostic factor for BCR. Incorporation of our signature into traditional risk classification might further stratify patients with different prognosis, which could assist practitioners in developing clinical decision-making.
