Blunt Abdominopelvic Trauma Complicated by Traumatic Testicular Dislocation in a 19-Year-Old Male Patient: A Case Report.

JBJS Case Connect 2021 07 22;11(3). Epub 2021 Jul 22.

Department of Urology Surgery, Puerto Rico Medical Center, University of Puerto Rico, Medical Sciences Campus, San Juan, Puerto Rico.

Case: A 19 year-old male patient presented with testicular dislocation after abdominopelvic trauma. During open reduction and internal fixation, consult to urology was placed after discovering the presence of the intra-abdominal testicle. The testicle was repositioned into the scrotum with orchiopexy, and pelvic fixation was completed with 1 sacroiliac percutaneous screw and pubic symphysis fixation. Postoperative recovery was uneventful, and the patient was discharged home on postoperative day 3.

Conclusion: Testicular dislocation is an uncommon finding after blunt abdominopelvic trauma; hence, it may be overlooked. Prompt diagnosis of testicular dislocation given the need for operative management to preserve testicle viability is crucial.

Penile cancer disparities in Puerto Rican men as compared to the United States population.

Int Braz J Urol 2012 Nov-Dec;38(6):728-38

Department of Health Services Administration, Graduate School of Public Health, Medical Sciences Campus, University of Puerto Rico, Puerto Rico.

Purpose: This study compares incidence and mortality of penile cancer in Puerto Rico (PR) with other racial/ethnic groups in the United States (US) and evaluates the extent in which socioeconomic position index (SEP) or its components influence incidence and mortality in PR.

Materials And Methods: Age-standardized rates were calculated for incidence and mortality based on data from the PR Cancer Registry and the US National Cancer Institute's Surveillance, Epidemiology and End Results program, using the direct method.

Results: PR men had approximately 3-fold higher incidence of penile cancer as compared to non-Hispanic white (Standardized rate ratio [SRR]: 3.33; 95%CI=2.80-3.95). A higher incidence of penile cancer was also reported in PR men as compared to non-Hispanic blacks and Hispanics men. Mortality from penile cancer was also higher for PR men as compared to all other ethnic/racial groups. PR men in the lowest SEP index had 70% higher incidence of penile cancer as compared with those PR men in the highest SEP index. However, the association was marginally significant (SRR: 1.70; 95%CI=0.97, 2.87). Only low educational attainment was statistically associated with higher penile cancer incidence (SRR: 2.18; 95%CI=1.42-3.29).

Conclusions: Although penile cancer is relatively uncommon, our results support significant disparities in the incidence and mortality rates among men in PR. Low educational attainment might influence the high incidence of penile cancer among PR men. Further studies are strongly recommended to explore these disparities.

New developments in the treatment of localized penile cancer.

Urology 2010 Aug;76(2 Suppl 1):S36-42

Servicio de Urología, Instituto Valenciano de Oncología, C/Beltran Baguena 8, Valencia, Spain.

Objectives: To analyze the current trends in local therapy approaches in patients with penile carcinoma.

Methods: The relevant published data since 2000 were reviewed; important series published before 2000 were also included. The reports were classified according to the level of evidence. Review studies and others indirectly related to the topic were also included but not classified.

Results: New information has suggested that surgical margins of only a few millimeters might be adequate for most localized tumors. A trend toward the use of more conservative therapies instead of amputative surgery has been observed, especially in developed countries. Although the local recurrence rate has been greater after conservative therapies than after amputative surgery, this increased rate does not seemed to have had a negative effect on cancer-specific survival. The quality of life has been superior after conservative procedures with preservation of the penis that seems to give the best results with regard to sexual function. Reconstructive surgery can be performed in selected patients after amputative surgery.

Conclusions: Although the level of evidence is low, conservative therapies can be recommended for selected patients with penile carcinoma. Despite the trend for conservative approaches, these patients need psychological support.

Extramedullary plasmacytoma invading the bladder: case report and review of the literature.

Urol Oncol 2003 Nov-Dec;21(6):419-23

Department of Urology, University of Puerto Rico, San Juan, Puerto Rico, USA.

Multiple myeloma is characterized by neoplastic proliferation of a single clone of plasma cells engaged in the production of a monoclonal protein. This condition affects mainly the bone marrow, but extramedullary manifestations can be seen in any organ. Urinary bladder involvement is extremely rare, with only 14 cases reported in the literature to our knowledge. Herein, we report a large extramedullary bladder plasmacytoma arising in a patient with history of multiple myeloma. A 78-year-old woman with history of multiple myeloma, currently in remission, presented with a large intravesical tumor. Because the tumor was considered to have characteristics of anaplastic neoplasm from transitional cell origin with evidence of deep muscular invasion, a radical cystectomy was performed. A subsequent microscopic evaluation of the cystectomy specimen revealed round cells with an eccentric cartwheel-like nucleus suggestive of plasmacytoma. The diagnosis was further confirmed with immunohistochemical studies. It is difficult, according to the literature, to distinguish bladder plasmacytoma from anaplastic transitional cell tumors. It is important to provide the pathologist with an appropriate history and to have a high index of suspicion for bladder plasmacytoma in patients with previous diagnosis of multiple myeloma and bladder mass.

Neoadjuvant androgen ablation before radical prostatectomy in cT2bNxMo prostate cancer: 5-year results.

J Urol 2002 Jan;167(1):112-6

Department of Urology, University of Miami Medical School, Miami, FL, USA.

Purpose: In the initial report of the Lupron Depot Neoadjuvant Prostate Cancer Study Group patients who received 3 months of androgen deprivation had a significant decrease in the positive margin rate. We monitored these patients for 5 years and to our knowledge present the longest followup of any neoadjuvant trial.

Materials And Methods: A multi-institutional prospective randomized trial was performed between February 1992 and April 1994 involving patients with stage cT2b prostate cancer, including 138 who received 3 months of leuprolide plus flutamide before radical prostatectomy and 144 who underwent radical prostatectomy only. Patients were followed every 6 months with serum prostate specific antigen (PSA) testing for 5 years. Biochemical recurrence was defined as PSA greater than 0.4 ng./ml.

Results: At 5 years there was no difference in the biochemical recurrence rate. PSA was less than 0.4 ng./ml. in 64.8% of the patients in the neoadjuvant androgen ablation plus prostatectomy and 67.6% in the prostatectomy only group (p = 0.663).

Conclusions: Although 3 months of androgen deprivation before radical prostatectomy resulted in an apparently significant decrease in positive surgical margins, a 5-year followup does not indicate any difference in the recurrence rate. Until studies document improvement in biochemical or clinical recurrence with longer periods of treatment, induction androgen deprivation before radical prostatectomy is not indicated.
