Validation of targeted microsurgical spermatic cord denervation: comparison of outcomes to traditional complete microsurgical spermatic cord denervation / 亚洲男科学杂志(英文版)

The aim of this study was to validate the effectiveness of targeted microsurgical spermatic cord denervation (MSCD) of the trifecta nerve complex in comparison to traditional full MSCD with complete skeletonization of the spermatic cord in men with chronic orchialgia. Retrospective chart review was performed by a single fellowship-trained microsurgeon between 2011 and 2016. Patients had follow-ups at 6 weeks, 6 months, and 1 year postoperatively. Thirty-nine men with chronic orchialgia underwent full MSCD between 2011 and 2013. In July 2013, after the publication of an anatomic study with identification of Wallerian degeneration of the trifecta nerve complex in men with chronic orchialgia, the technique was changed to targeted MSCD. From July 2013 to March 2016, 43 men underwent targeted MSCD. When comparing the full MSCD group to the targeted MSCD group, there was no significant difference in resolution of pain (66.7% vs 69.8%, P = 0.88), no difference in partial relief of pain (17.9% vs 23.3%, P = 0.55), and no difference in failure to respond rates (15.4% vs 7.0%, P = 0.22) between the two groups. There was no difference in mean change of visual analog pain scale scores between the two groups (P = 0.27). Targeted MSCD had a shorter operative time (53 min vs 21 min, P = 0.0001). Targeted MSCD offers patients comparable outcomes to traditional full MSCD, with a shorter operative time, a less technically challenging surgery, and potentially less risk to cord structures which should be preserved.

Denervación de cordón espermático asistida con lupas para el tratamiento del dolor testicular crónico idiopático / Spermatic cord denervation assisted with magnifying glasses in the treatment of idiopathic cronic testicular pain

Presentar una serie clínica de doce pacientes sometidos a denervación de cordón espermático asistida con lupas como tratamiento del Dolor Testicular Crónico ldiopático (DTCI). Pacientes y métodos: Diecisiete pacientes (rango de edad 18 a 70 años) con DTCI no respondedores a analgésicos orales fueron enrolados prospectivamente en la primera etapa del estudio. Se realizó un bloqueo del cordón espermático con Bupivacaína a todos los pacientes. Aquellos pacientes que respondieron al bloqueo (n= 12) fueron sometidos a denervación del cordón espermático asistida con lupas (magnificación 3. 5x) por via subinguinal. El seguimiento incluyó un ecodoppler testicular a los siete días post cirugía y Escala Visual Análoga (EVA) del dolor a los 3 y 6 meses. Resultados: La duración promedio de la cirugía fue de 70 minutos (rango: 50 a 90 minutos). En el control de los siete días los doce pacientes presentaron un ecodoppler normal sin evidencias de isquemia en ninguna de las unidades testiculares sometidas a cirugía (n= 13). Respecto de la EVA a los tres y seis meses, nueve pacientes (75 por ciento) estaban completamente libres de dolor con un EVA igual a O. Tres pacientes persistían con molestias, dos con un EVA de 1 que no requerían analgésicos, y uno con EVA de 2 que requería analgésicos de manera intermitente. Dos pacientes fueron reoperados 6 y 8 semanas después de la cirugía primaria, uno por un hematocele y el segundo por un linfocele, ambos evolucionaron de manera favorable con ecodoppler normal después de la segunda cirugía. Conclusión: La denervación de cordón espermático asistida con lupas es una alternativa eficaz para el tratamiento del DTCI y puede constituirse en una buena alternativa terapéutica para el manejo de estos pacientes...

To present a clinical series of twelve patients that underwent loupe assisted spermatic cord denervation as a treatment for idiopathic Chronic Testicular Pain (ICTP). Patients and methods: Seventeen non responders to oral analgesics patients (age range 18 - 70 years) with ICTP were prospective/y enrolled in the first stage of the study. A spermatic cord block with bupivacaine was performed in all patients. Twelve patients who responded to the bupivacaine cord block underwentloupe assisted (3. 5x magnification) spermatic cord denervation through a subinguinal/ approach. Postoperative follow-up included color doppler ultrasound of the testes seven days after surgery and Visual Analog Scale (VAS) pain questionnaire at 3 and 6 months. Results: The median operation time was 70 minutes (range 50 - 90 min). Seven days after surgery all patients had a normal color Doppler ultrasound without evidence of ischemia in any of the operated testes (n=13). At three and six months after surgery nine patients (75 percent) were absolutely pain free (VAS=O). Three patients remained with pain; two had a VAS 1 that did not interfere with daily activities and required no analgesics, the third patient had a VAS 2 and occasionally required analgesics to manage pain. Two patients needed reoperations, 6 and 8 weeks after primary surgery, one for hematocele and another for lymphocele, both had a favorable outcome and normal color doppler ultrasounds after the second surgery. Conclusion: Loupe assisted spermatic cord denervation is an efficient alternative for the management of ICTP and may become a good therapeutic option for these patients...

Microsurgical testicular denervation for the treatment of chronic testicular pain initial results

INTRODUCTION: Chronic testicular pain remains an important challenge for urologists. Currently, the treatment plan is primarily empirical, with the first approach consisting of clinical measures. However, some patients remain in pain despite a conservative treatment protocol and, for them, it is possible to perform a surgical procedure that involves severing the scrotal and spermatic branches of the genitofemoral and ilioinguinal nerve fibers. METHODS: In our institution, 60 patients were evaluated and treated for idiopathic chronic testicular pain between January 2003 and July 2007. Priority was give to clinical treatment, which evolved from simple to more complex measures. Microsurgical treatment was performed on those who experienced no considerable pain relief (10 individuals in our study). RESULTS: Over a twenty-four-month follow-up period, 70 percent of patients showed complete remission and 20 percent exhibited partial relief from pain.
